Topic: Can't send out emails

==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====
- iRedMail version (check /etc/iredmail-release): 1.4.2 PGSQL edition.
- Deployed with iRedMail Easy or the downloadable installer? via apt-get
- Linux/BSD distribution name and version: Debian 11 x64
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): PGSQL
- Web server (Apache or Nginx): Nginx
- Manage mail accounts with iRedAdmin-Pro? No
- [IMPORTANT] Related original log or error message is required if you're experiencing an issue.
====

Setup looks like working fine in general, can access mailboxes via RoundCube and via IMAP by desktop and mobile clients, and all mail clients can receive and send emails.
But sent email doesn't leave the server. Tried different destinations and none received anything (did check Spam folder).
And few days later I got this bounce in my postmaster mailbox:

-----8<-----
This is the mail system at host mx1.noXXXX.XX.

I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can
delete your own text from the attached returned message.

The mail system

Two questions:

1. Not clear if it's related or not.

2. How do I check what's happening with the sent email and find the root cause of the issue?

Thank you.

Re: Can't send out emails

Can you check your amavis status with 'service amavis status'? Should show: "Active: active (running)"

Hi,

Are you changed the DKIM key?

If yes, you need the modify the next file: /etc/amavis/conf.d/50-user
With the next documentation: https://docs.iredmail.org/sign.dkim.sig … omain.html
The location of the config file is in this web: https://docs.iredmail.org/file.locations.html#amavisd

Best regards

Re: Can't send out emails

Thank you for the links, I'll check. But I haven't touched DKIM key.
Although I wasn't able to add DKIM to the DNS, as I have domain on hover.com and I got error that TXT value is too long. I created support ticket with them, but no response yet. Not sure if it's the reason, or there is more to it.

Re: Can't send out emails

Actually, that specific domain wasn't on hover.com (I'm trying multiple domains in parallel), so I was able to add DKIM record to DNS, not sure if it'd help or not.

Also, what's the best place to check what's going on with the sent email within my server?

Thank you.

Re: Can't send out emails

what is the result of mailq ?

if yourself get a bounce msg from your own mailserver, something must be really wrong

also, /var/log/mail.log would help a lot in this case

Re: Can't send out emails

first of all, clear the mailq:

postsuper -d ALL

it seems the mailq tries to deliver the mails but is failing to do so, so it gets stuck

after that, do the following:
apt-get purge clamav
apt-get install clamav clamav-daemon

reboot the server afterwards and look if it is working again

Re: Can't send out emails

Hmm.

```
# apt-get install clamav-daemon
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
clamav-daemon is already the newest version (0.103.3+dfsg-0+deb11u1).
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.
```

And shouldn't iRedMail install it automatically?

Btw, I have the same issue on another machine on Linode (this one is on DigitalOcean), with the same symptoms and `clamav-daemon` is installed there as well.

Both are Debian 11.

Re: Can't send out emails

Hmm, something is wrong with my setup:

purged, installed, rebooted.

Did `tail -f` on the mail.log, and this is what I got right after I hit Send in my mail client:

Re: Can't send out emails

/etc/amavis/conf.d/50-user

@bypass_virus_checks_maps = (1); # controls running of anti-virus code

this disables clamav

restart amavis after and try sending mail again

Re: Can't send out emails

That worked. Thank you.

Also, clamav is strange, same issue on the same two boxes (Do and Linode, both Debian 11), fresh iRedMail install.

clamav-daemon isn't started, when trying to start nothing happens, clamav.log is empty.

Here is service status:

What are the system specs? especially how much RAM ?

Re: Can't send out emails

wow, ok

Also, clamav is strange -> how can you expect these specs to work? clamav ALONE needs ~1.5GB ram, not to mention all other services, 4GB are MINIMUM to keep a iredmail server alive, and that is on the very low end

Woah. I assumed 4GB is for production server is some real life traffic, not just for my test setup with one test email a day.

Also this setup (https://github.com/sovereign/sovereign) has very similar "shopping list" (Dovecot, Postfix, Postgres, Roundcube, etc) and they measure memory in MB, so it kind of fueled my assumption further.

Curious what does clamav do with that 1.5GB of RAM

--

Thank you for all the help and following through with my issues.

PS. Do you think it would be helpful to have memory check during iRedMail install script, so it could yell at users like me, and prevent them from multi day headache?

exec three commands

tcptraceroute smtp.gmail.com 25
tcptraceroute smtp.gmail.com 465
tcptraceroute smtp.gmail.com 587

and compare outputs
