Hi @Alexandre, I am also getting this error now (Smtp.ConnectAsync timeout), I believe that this one happens when I set smtp to port 25 instead of 587, just a guess.
1. Which is strange is that it works from time to time, and out of the blue it stops, but the logs should clarify that:
2. I am no IT expert, but I noticed that if I telnet to port 25 (to escritorio.blarafernandes.com:25) I allways get a response form my server. But if I try on ports 587 or 143, it’s not allways the case:
3. If I telnet to the my local server IP (10.0.0.150), I get a server response on all these ports (25, 143 and 587). Is there something bloking these ports from time to time? I have disabled all firewalls (ubuntu server, router, router antivirus…). If I connect from my mobile network I can get a telnet response on all these 3 ports. So I am rulling out my ISP blocking something.
4. My other guess, is that it has something to do with this config screen, witch gives me an port 8081 error if I change anything (mysql access?).
But it seems to works the default IP 172.18.0.4, which I have no clue as where it came from.
I believe that there might be a way to test with other IMAP port 993 ou POP3 110, but still the SMTP should be working on port 25 (can we force to use it on the Mail Server container?).
