Mail-Roundcube-Exim-Dovecot issue(s)

[suassive]

I did a completely new installation of VestaCP twice now, the first time I installed it I got the same error(s) I have been having
I tried fixing it by removing Exim + Dovecot and re-installing those packages.
I still get the same exact errors which are these

As you can see it's grayed out because the services aren't running but that's one of the error(s) as I did the new installation again (reimaging my VPS and installing Vesta) the services don't start by default. So before to start the services, I did

Code: Select all

apt-get remove exim4-*
apt-get purge exim4-*
apt-get remove dovecot-*
apt-get purge dovecot-*
apt-get autoremove
apt-get install exim4
apt-get install dovecot

They install fine, and the services then start just fine, but for some reason Exim keeps shutting down on it's own.
Then roundcube gives me the error "Connection to storage server failed"

I am confused as to what's going wrong exactly. I'm assuming it could be the configuration files? but I'm not sure. Any help would be much appreciated. Thank you

Which server OS do you use? You've already looked at the log files? There you might find what is going wrong.

Sorry I forgot to mention that, I use Ubuntu 14.04
and no I haven't looked into those yet...not sure how really.

What's in logs? When you restart services in console, what error you get?

I can't seem to find the Exim4 logs, the only one that is showing is the Dovecot log

Address already in use: daemon abandoned

Ta da ;-)
You get in.
Let's see, what service at 25 port:

Code: Select all

netstat -tulpn | grep :25

and you can try something like this:

Code: Select all

killall exim
service exim start

Thanks for your help @skurudo
