Problem connecting with desktop client
I run my home server under Rocky Linux 9. The server is modem / router and as such has two firewall interfaces; internal and external.
Dovecot version is dovecot-2.3.16-8.el9.x86_64 kernel is: 5.14.0-284.18.1.el9_2.x86_64
My domain is wo-lar.com
Postfix and Dovecot are up and running, and I can send and receive emails from CLI.
But I cannot connect from desktop clients. I get the following error message: Server message: Can't connect to host "tcp://wo-lar.com:143"
I tried to telnet from my desktop and server. Results are the same:
- I always get a connection refused: telnet wo-lar.com 143 telnet / telnet <Server LAN IP> 143. On server only: telnet 127.0.0.1 143
- telnet wo-lar 143 (without .com!) establishes a connection [root@home wp.rauchholz]# telnet wo-lar 143 Trying 79.152.236.25... Connected to wo-lar. Escape character is '^]'. OK [CAPABILITY IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE LITERAL+ STARTTLS AUTH=PLAIN AUTH=LOGIN] Dovecot ready.
I went through all kinds for conf files and search for wo-lar string, but can't find it anywhere
Where is the mistake hiding?
Thanks for helping.

Hello Aki,
Thanks for picking up the topic.
[root@home wp.rauchholz]# doveconf listen listen = ipv4
root@home wp.rauchholz]# ss -lnpt | grep dovecot LISTEN 0 100 79.152.236.25:143 0.0.0.0:* users:(("dovecot",pid=803194,fd=35))

What is your
listensetting in dovecot.conf?you can check with
doveconf listenAki
Try
listen = 0.0.0.0
or
listen = 79.152.236.25, 127.0.0.1
instead.

doveconf listenAki

What I did and fixed the problem was to reset the listen value the default: "listen = *, ::" I am running my home server under dynamic DNS. Therefor I cannot set the IP
Thanks for pointing me in the right direction.
