Hi Vytautas, I was also getting this error after upgrading to 0.60-2 on Debian.
In order to get rid of it, I regenerated my esmtpd and imapd self-signed certificates using /usr/sbin/mkesmtpdcert and /usr/sbin/mkimapdcert. These create /usr/lib/courier/esmtpd.pem and /usr/lib/courier/imapd.pem, so move any existing versions out of the way before you run the utilities. The configuration files used in generating the certs are /etc/courier/esmtpd.cnf and /etc/courier/imapd.cnf. I also needed the following links: ln -s /usr/lib/courier/esmtpd.pem /etc/courier/esmtpd.pem ln -s /usr/lib/courier/imapd.pem /etc/courier/imapd.pem Best regards, Chuck -----Original Message----- From: Vytautas Kasparavicius [mailto:vyt...@freemail.lt] Sent: Wednesday, March 02, 2011 8:46 AM To: courier-users@lists.sourceforge.net >> Courier Users List Subject: [courier-users] Error generating ip address Hello, How to investigate which ip address generated folowing error: Mar 2 15:48:37 mail imapd-ssl: couriertls: accept: error:14094416:SSL routines:SSL3_READ_BYTES:sslv3 alert certificate unknown Thanks. ------------------------------------------------------------------------------ Free Software Download: Index, Search & Analyze Logs and other IT data in Real-Time with Splunk.
