Hi list!

I'm writing because of an issue I'm having with my Postfix-Dovecot installation. Everything's working fine but when an IMAP client is idle for some time, Dovecot automatically logs it out.

Jul 26 14:01:16 mail dovecot: imap(nicolas@devels.es): Disconnected: Logged out bytes=1271/7439

This entails errors when trying to send e-mails after this auto logout, such as:

host devels.es[91.215.158.237] said: 550-Please turn on SMTP Authentication in your mail client, or login to the 550-IMAP/POP3 server before sending your message.

Which result in a very annoying and continuous proccess of restarting my mail client.

Is there a way to avoid this auto-logout, or at least configure the time after I want idle clients to auto-logout?

Thank you very much!

Nicolás

I would suggest that you configure the smtp submission port facility on your mail server and set your imap/pop clients to send that way. The "pop before sending" approach is a fairly old and broken hack (including submitting via port 25, which is frequently blocked by connectivity providers).

With sendmail the submission port option is basically configured by default. I don't know about postfix, but I suspect it is there too.

Thanks for your responses!

I just tried configuring the submission port on postfix but the problem persists even sending by port 587.

About what Harald said, I guess I initially missed the point of the problem, it was just my conclusion because that error happens always after the logout message appears, and SMTP authentication is set on my client, so I deduced the problem had something to do with the logout thing. The curious thing is it just happens with SMTP, not with POP3/IMAP protocols.

Thanks again!
