We are using mailman with gmail account, connected through imap and everyday we get several exception mails with closed stream exception.

An IOError occurred in background at 08 February 2015 :

Do you have any suggestions how to fix it ?

The current master branch contains retry logic to ensure the daemon is kept running: https://github.com/titanous/mailman/commit/153767a1c91ed431577c04d1539b06f9054aca08

I assume the imap server closes the connection after a certain timeout.
