docker-mailserver: Cant send email on the server itself

Subject

I cant send emails on the server from one mailbox to another.

Description

Hello everybody 😃 I am trying to get this mailserver running but I am failing on some point and I dont really know where… I just set the server up with the documentation and I tried sending E-Mails to GMail, that didnt work for authentication reasons or sth like that… Now I created a second mail account on the server and try to send e-mails between both of them, but they dont appear in the others mailbox. I dont know why, does anybody know what might happen there? Because its all on one server it cant be a network problem like ports/dns records, aight?

Thats the log after sending the email, I hope its all the important part, if not please just ask.

When I go for ./setup.sh email list I get those 2 mailboxes I created

* me@mail.domain.de
* test@mail.domain.de

The sent emails appear in the sent folder of the mailbox but the other mailbox does not receive them.

Thanks for any help, have a good one!

Hello everybody! I figured sth out… I had the mailserver running on mail.domain.de and so I created my mailboxes like “me@mail.domain.de”, but at that moment this domain (mail.domain.de) gets added as vhost and from that on I get this warning, like mentioned in the warning text. So I removed my data folder and started all from scratch, this time I added “me@domain.de”, so this domain got added as vhost and it works just fine! There seems to be a problem when adding mailboxes with the same domain/host the mailserver is running on, is that intentionate? Atm I can just receive mails from GMail and cannot send any to gmail, because of authentication reasons, even tho I setup spf and DKIM, but maybe it just need some time…

I guess I’m closing this because my problem is solved. If I can help you with some tests just inform me.

da-wilky on Apr 24, 2022

Hey guys, I did some more tests on that one…

Now I got 2 mailboxes added:

me@domain.de
test@mail.domain.de

My Mailserver is still running on host mail.domain.de.

The mailbox me@domain.de is working fine, I can send and receive emails without any problems. The mailbox test@mail.domain.de can send emails but cannot receive any. As soon as there is an email coming for that mailbox I’m getting the good old warning (warning: do not list domain mail.domain.de in BOTH mydestination and virtual_mailbox_domains) and the email can not be delivered.

da-wilky on Apr 21, 2022

I didn’t send any emails, as I thought the warning came on DMS startup. But I don’t have time right now to test further.

Like mentioned above, on startup I had the same output like he got.

My output never changed on startup, it was always like:

I was just getting the warning message when sending/receiving emails, I dont know if @casperklein also tried that out. I just created 2 mailboxes (me@mail.domain.de and test@mail.domain.de), connected via IMAP with Thunderbird and then tried to send an email from me to test.

That resulted in the following:

I was only getting this warnings, when receiving or sending (I dont really know which one of them) emails to/from the mailbox, on startup I didnt got that warning too.

warning: do not list domain mail.domain.de in BOTH mydestination and virtual_mailbox_domains

And I use hostname: mail + domainname: domain.de at the moment, without an override inside the env. EDIT: I now tried hostname: mail.domain.de and its also working fine. (All with the me@domain.de mailbox)

da-wilky on Apr 21, 2022

Okay, thank you! Now I have sth to work on, I’ll text you again if I’m really stuck or get it to work.

I have no aliases or sth, I only added those 2 mailboxes and the DKIM keys with the setup.sh.

This is not normal and likely your problem. That’s why I suggested to test with OVERRIDE_HOSTNAME. Do you have setup aliases or something?
