listen = *%lo:

[nanathlor]

Can someone please quickly explain to me what the new cfg file listen setting syntax means?

for gateway.cfg we were imap_port = 143 default is now imap_listen = *%lo:143 which refuses all imap external connections until you remove “lo”.

Thanks in advance.

‘lo’ means localhost - it’s probably binding and only accepting connections to 127.0.0.1 - You can verify by looking at the output of netstat -tunap and see what address :143 is bound to.
