dovecot rejecting connects
I am a newbie to dovecot but not postfix and centos
I created a new VM with Centos 8 and installed dovecot and postfix.?
Postfix is working fine but dovecot rejects connections from anything
but the local machine.
Locally

Is teh VM switchted or routed with the LAN interface?

Which make it pretty clear that it has nothing to do with
dovecot as such as that's aresponse from the TCP/IP-stack ...

Duckduckgo-ing "icmp 3 13" delivers as the 1st link
http://www.networksorcery.com/enp/protocol/icmp/msg3.htm and
13 seem to indicate "Communication Administratively Prohibited."
Your turn;-)
