sudo cat /var/log/exim4/paniclog

watch error

Also noticed that Exim4 takes a long time to process incoming connections. I tried Postfix, it works just fast, but in the control panel the status of the mail server is immediately "not set"

perhaps the truth is in the file "exim4.conf.template" the field "rfc1413_query_timeout"

Sorry, I wrote all this via google translate, English is not my native language

I was the only one faced with the fact that all outgoing letters are not signed with a DKIM signature and in fact are considered spam due to an erroneous config generated by TinyCP Dear developer, correct the error, otherwise after reboot you will have to change the exim4 config

And if it is good to "kick" your panel, then it starts working)) Take the guys to yourself, I'm ready to help for some money)
