<![CDATA[Warnings when starting mail service. `client_limit` too low.]]>I am seeing these warnings in the logs when I restarted the mail container in Cloudron. It seems like the client_limit should be increased according to these warnings.

Counted for protocol services with service_count != 1: service managesieve-login { process_limit=100 } + service pop3-login { process_limit=500 } + service lmtp { process_limit=100 } + service imap-urlauth-login { process_limit=100 } + service imap-login { process_limit=500 }

I have put this for next release.

I guess setting it to 1300 or 1500 for example should suffice and suppress the warning messages.

This is likely not the common use-case with Cloudron.
