[Fetchmail-users] IDLE Socket error After IP reconnect

[<Lol...@we...>]

Hi,

New User here.

Setup: Running a Python script starting one instance for each of multiple mail accounts in IDLE mode leveraging individual $FETCHMAILHOME environment variables like this:
https://www.linuxquestions.org/questions/linux-software-2/correct-fetchmail-with-idle-and-multiple-servers-config-642089/

Fetchmail runs behind a router with Dynamic IP.

Occationally (and particularly After IP resets), I receive the following error for each instance and the script restarts the fetchmail instances:

Nov 01 08:48:54 fetchmail: Received BYE response from IMAP server:  TIMEOUT
Nov 01 08:48:54 fetchmail: re-poll failed
Nov 01 08:48:54 fetchmail: socket error while fetching from…

I assume this is due to the IP change and the connection cannot be re-established. I think this will Not harm fetchmail’s functionality and I can safely restart it without fearing any mail will be lost or not fetched.

Can you confirm this understanding and maybe explain better what is Happening and what an elegant way is to mitigate?

Thanks!
