I run my home server under Rocky Linux 9. The server is modem / router and as such has two firewall interfaces; internal and external. 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 conenction [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 checked firewalld settings. Port 143 is open on my laptop as well as on the server I went through main.cf and verified myorigin, myhostname, mydomain, myorigin. Domain is spelled correctly in all cases. Receiving mail: inet_interfaces is set yo all Where is the mistake hiding? Thanks for helping Wolfgang
