The certificates of the courier imapd-ssl and pop3d-ssl were expired. After some searching I found how to renew them:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | sudo aptitude install courier-pop-ssl nano /etc/courier/imapd.cnf #edit the CN nano /etc/courier/pop3d.cnf #edit the CN mv /usr/lib/courier/pop3d.pem /usr/lib/courier/pop3d.pem.old mv /usr/lib/courier/imapd3d.pem /usr/lib/courier/imapd.pem.old /usr/lib/courier/mkimapdcert /usrlib/courier/mkpop3dcert cp /usr/lib/courier/pop3d.pem /etc/courier/ cp /usr/lib/courier/imapd.pem /etc/courier/ /etc/init.d/courier-authdaemon restart /etc/init.d/courier-imap restart /etc/init.d/courier-imap-ssl restart /etc/init.d/courier-pop restart /etc/init.d/courier-pop-ssl restart |
With thanks to this post.
If first thought that /usr/lib/courier/mkimapdcert generates the certificates in the wrong path. But on another server the cp command complained that the two files were identical. So it looks like they are hard-linked or something…
