1. Introduction

Who can get one. If you are a core team member of a project executed by the Edgeryders company, or as a volunteer have a designated role in the community (such as helping with community management), you can get an e-mail address.

What it is – technically. Your e-mail address will be a full mailbox that allows both sending and receiving, the latter via IMAP and POP3 and by forwarding all e-mails to your regular e-mail address as a copy. Usually you will set up the sending, while receiving e-mails to your regular e-mail address. If you don’t want the copies and instead want to access this account directly with IMAP or POP3, tell @matthias.

Personal and role-based addresses. We have two formats of e-mail addresses at Edgeryders. First, a personal e-mail address, which will usually be of the form <firstname> By default, a copy of all incoming e-mails is sent to your regular e-mail address, and only to that. Second, role-based e-mail addresses. These are created for roles within Edgeryders (such as, and access to them and / or forwarding to their own regular e-mail address is given to the person or persons having that role at the time.

Make your own backups! Note that, while your e-mail account will store copies of e-mails you receive, we do not guarantee the long-term data integrity of your e-mails. So back up your Edgeryders e-mails yourself! When you receive them forwarded to your regular e-mail address, as is the default, own backups are simple as Edgeryders’ e-mails would automatically be included when your regular e-mails are backed up.

About the old forward-only addresses. Before 2017-06, we have handed out e-mail addresses that were pure forwarders to your regular e-mail address, without support for sending via SMTP. Some still have these accounts, but we will switch them to full mailboxes as well. The reason is that the way of sending from these addresses (by adding an identity for your address to your regular e-mail account) is no longer possible in GMail, and became too difficult and cumbersome with all other e-mail providers due to “obligatory” anti-spam measures like SPF.

2. How to receive and send e-mails with Gmail

Receiving. No setup is needed, as normally all e-mails arriving to your e-mail address will be forwarded to your regular e-mail address – presumably the Gmail address associated with this Gmail account. Only if you opted out of the forwarding, you have to find a different solution. See the Gmail help article “Check e-mails from other accounts” for that.

Sending. Summary: In the GMail web interface, use “:gear: → Settings → Account and Import → Send Mail as: → Add another e-mail address” and enter your SMTP settings (server and your login credentials).

If you have difficulties, see the detailed instructions in “Step 1” to “Step 3” sections of the Gmail help article “Send emails from a different address or alias”.

If you still have difficulties, see our annotations on the Gmail help article below.

  • On “Step 1: Add an address you own”: the information to enter into the forms is:

    • your name: just your name, no way to make a mistake as every value will be accepted by the form
    • address you want to send from: use the full e-mail address, such as
    • SMTP server:
    • username: use the full e-mail address given to you, usually it has the form
    • password: use the password given to you; it is the same as for receiving e-mails
    • Treat as an alias: yes (the default). Else Gmail would hide e-mails sent to your address and then forwarded to your Gmail address. This setting is documented here.
  • On “Step 2: Confirm the address”: The confirmation e-mail will regularly arrive to your Gmail account, so simply find and click the confirmation link there. Also check your spam folder if it does not show up in your inbox. If you click on the “confirm” link but no window opens (that tells you to either click a link or enter a code received by e-mail), try switching windows (Alt + Tab on Windows) as the window might be already open from an earlier attempt.
       (Explanation: by default, unless you expressly want it differently, all e-mails to your e-mail address will be forwarded to your regular e-mail address. This will normally be the same Gmail address where you are logged in right now to set up sending from your address. So the confirmation e-mail by Google will also arrive at that Gmail address. If you did indicate you don’t want copies to your regular e-mail address, you have to set up IMAP or POP3 access to your e-mail address first, in order to see the confirmation e-mail. See below for instructions.)

  • On “Step 3: Change the “From” address”: You have to do this step for every new e-mail you write that you want to come from your e-mail address. Because, your default e-mail address is still your Gmail address, and you probably want to keep it that way.

3. How to receive and send e-mails with Thunderbird

This setup process is different but similar in all desktop and webmail software. As an example, here is the process in Thunderbird, a free and open source advanced desktop mail client for Windows, Mac OS and Linux.

  1. Click “Edit → Account Settings” in the menu.

  2. Click “Account Actions → Add Mail Account …”.

  3. In the form, enter the following:

    • Your name: (just enter your name, no way to enter anything wrong)
    • Email address: enter as given to you, usually it has the form
    • Password: enter the password given to you
  4. Click “Continue”, then click “Manual config” (because Thunderbird is unable to automatically fill in the right values for addresses).

  5. Enter the following values in the lower section of the form. Most will be already there, guesed correctly by Thunderbird. The two values you will have to fix are “Username: Incoming” and “Username: Outgoing”. They have been marked with icons in the list below.

    • Incoming IMAP: (means, if you choose protocol IMAP, the default and more modern variant)

      • Server hostname:
      • Port: 143
      • Authentication: Normal Password (This means, transmitting the password in non-hashed form. This is secure because of STARTTLS. It seems that our ISPConfig-configured mail server does not (yet) support MD5 etc. for hashed password transmission.)
    • Incoming POP3: (means, if you choose protocol POP3)

      • Server hostname:
      • Port: 110
      • Authentication: Normal Password
    • Outgoing:

      • Server hostname:
      • Port: 587
      • Authentication: Normal Password
    • Username:

      • :bangbang: Incoming: the full e-mail address given to you, usually it has the form
      • :bangbang: Outgoing: the full e-mail address given to you, usually it has the form
  6. Click “Done”. Thunderbird will now try the password you gave, and fetch e-mails from the account.

  7. When Thunderbird starts to fetch e-mails from your account for the first time, it will warn you that the SSL certificate could not be accepted because it is “self-signed”. Ignore that warning permanently (“Store security exception.”). If you use other software to access an e-mail account without an interactive interface, such as Discourse, you have to configure it to not verify the SSL certificate. (Providing a real SSL certificate is on @matthias’ to-do list.)

4. Special case: How to send e-mails using a third-party SMTP server

This is only needed in special cases, such as when wanting to employ a third-party newsletter service like Mixmax for sending e-mails originating from addresses. Instructions:

  1. Ask @matthias to add the third-party SMTP server you want to the SPF record. (This is basically a public list of servers that are allowed to send from addresses, meant for spam control, and more or less obligatory to have these days.)

  2. If necessary, configure Gmail or your mail client to use this third-party SMTP server. Use the following values:

    • e-mail address: you can use any e-mail address that exists on as “From:” address, but in order to allow replies it should at least exist
    • username: the username for access you should have received from the third party operating this SMTP server
    • password: likewise, to be received from the third party operating this SMTP server

5. How to receive e-mails from role-based addresses

All our role-based e-mail addresses can forward to any number of other e-mail addresses. So by adding yours to the list of forwarding targets, you “sign up” to receive everything that goes to this address. We use this mechanism esp. for cases where we can only register one e-mail address for a specific purpose (such as at our accountants) but several people want to “be in the loop”.

At this time, we actively use the following role-based addresses (consider all others legacy or there for technical reasons only):

  • : Communication with our accountants and other finance related services.
  • : Reaching out to the Edgeryders community.
  • : Main contact address for the Edgeryders company.
  • : Edgerders conferences (?).
  • : Address associated with the Github organization account for Edgeryders.
  • : Communication with the Edgeryders Research Network.
  • : Contact address for technical issues related to domains, e-mail and webhosting. Also required by some old Internet standard. Not (yet) used as the e-mail address associated with our hosting contracts.

The process to add your address as a forwarding target is as follows:

  • If you are a member of the management board:

    1. Get the password for the ISPConfig user edgeryders from @matthias.
    2. Log in at with username edgeryders and the password you have received. Ignore SSL exceptions, and sorry about that.
    3. In the left sidebar, select “E-Mail Mailbox”.
    4. Click on the row of the e-mail address you are interested in.
    5. Add you e-mail address in line “Send copy to:”, separated with a comma “,” or comma and space from the others.
    6. Click “Save”.
    7. Once the red-circled “1” disappears from the top area of the page, your change is successful. You may test it by sending an e-mail to that address, but note that other people will get it, too.
  • If you are not a member of the management board:

    1. Ask @matthias (in Matrix chat or by direct message here on the platform) to add your e-mail address as forwarding target.

6. How to create an e-mail address

We can create e-mail addresses of the form This is used for communications of the Edgeryders company (our social enterprise), but we can also provide such addresses for community projects which are in some way officially backed and supported by the Edgeryders social enterprise.

Here’s how to create such addresses.

  1. This needs server admin panel access. If you don’t have the credentials for that, you should probably ask @matthias to do this task for you.

  2. Log in to the ISPConfig panel for server administration (will be this link some time after 2017-11 when the old link stops working).

  3. Go to “Email → Email Mailbox” and click “Add new Mailbox”.

  4. Fill in the form:

    • Put in the person’s name (so we can know which addresses in the list are still needed).
    • Configure the address to be
    • Set the password and copy it to your password manager or to tell the person whose address you are creating.
    • Put the forwarding target address into “Send copy to:”
    • Set “Spam filter: Normal”.
  5. Click “Save”.

For setting this new e-mail address up in an e-mail client to actually use it for sending and receiving e-mails, see: “Using e-mail addresses”.


Note: Previously, we did set people up with e-mail forwarder addresses only (since we consider these personal addresses personal communication and did not want to be responsible for maintaining the security and integrity of these e-mails on our servers). However, sending from this as a “From:” address while using your own e-mail account is no longer practically possible due to new anti-spam measures in e-mail enforced by Google etc. (SPF, DKIM). So now everyone is getting a full e-mail account, but we still take no responsibility to back up these e-mails or keep them safe. (We do keep backups of course, and do our best to keep the server safe.)

I am having trouble setting up my email address in Thunderbird. For my gmail acount my regular password wasn’t working in set up and after some research I learned I had to create an application specific password.

Has anyone else had this issue? Might you @matthias have any suggestions as to how to troubleshoot my password not being accepted in Thunderbird email account set-up?


I have tried the instructions from above section 3 with your e-mail address and the associated password I sent you by e-mail on 2017-10-30. Works for me.

This means you make some kind of mistake following the instructions, either when entering the username or copy&pasting the password. I guess it’s the username: Thunderbird cannot guess it correctly, so it’s the only thing to fix in the manual config form. You have to enter your full e-mail address as the username: I have updated the instructions above to make this step more prominent.

Hope it works now :slight_smile:


@matteo_uguzzoni I notice you don’t have a company address, can we get you one? That way we can get you full permissions to access relevant drives in our new Google enterprise account..


You can give Matteo access without needing an … Google Account for him. I propose that’s even the better option, as it’s considerably cheaper for us when using this as the default. Details.
