Do you have 1024 users which are using IMAP/SOGo at the same time?

First of All, I was expecting you to reply to this. Thank you for your time. I respect your valuable time and will try not to waste it.

And yes, I am uploading my email accounts onto a platform which creates a connection to my smtp server and I upload the accounts in bulk, so they create the connection simultaneously. Is there any way i can increase the connection limit?

My server has plenty of resources, it has 64GB Ram and 12 Dedicated cores running at 4.2GHz each.

Currently, I am testing their service so I need to increase this limit as much as I can.

You could try to use the extra.conf as described here:

https://docs.mailcow.email/manual-guides/Dovecot/u_e-dovecot-extra_conf/

Create the file and add this block (untested):

service imap {
  executable = imap
  user = vmail
  vsz_limit = 1G
  process_limit = 2048
}

DocFraggle Thanks a lot. It was a huge help. I will continue this if I the issue still persists.

@DocFraggle You probably answered my totaly different question too…
I’m 6 months hunting and testing for a decent replacement of Zimbra 8 OSE, tried numerous community editions to just find out it either lacks documentation, looks pretty and doesn’t work or does work and unmanageble.

Then today,.. I saw the demo of Mailcow, knew about it but walked away from anything docker-related.
Specifically because I have a lot of tuning in either postfix/dovecot/cyrus/httpd configs that are not available thru any webbased menu.

Knowing that poking directly in containers will end up with back-to-default once restarted.

Then you come up with this answer to customize/expand a certain config.
So there is hope!

Although the admin panel of mailcow seems to give me (almost) ALL I ever wanted, if it is “almost” then there is probably an escape in this way ;-)

Thanks

[unknown] I hope btw SOGo will fix my reported bug, because that is still the one withholding me from switching mailserver (Basic HTML-stuff, BODY-tag missing in any message, which renders badly in some clients when a BASE64 image is involved in the message)
