dragonfly mail agent: sending a testmail causes high system load
When sending an email from dragonfly mail agent to a mailserver in the local network, the system load
increases up to > 80%. The remote mailserver (Postfix) speaks TLS via port 587 (submission)
However, the email cannot be sent:
remote delivery deferred: Peer did not provide certificate: error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure
Since other mail servers - such as exim4, postfix, etc. - are able to send emails to the remote server,
I figure the problem is somewhere at the DMA.
This problem has been encountered on an IPFire (http://www.ipfire.org/) firewall system running on an
ARM-board. Please see https://bugzilla.ipfire.org/show_bug.cgi?id=11036 for the ticket in their bugtracker.
