Source: fetchmail
Followup-For: Bug #926928
I've checked the manpage for fetchmail. There was the following in the
stretch package:
--sslcommonname <common name>
(Keyword: sslcommonname; since v6.3.9)
Use of this option is discouraged. Before using it,
contact the administrator of your upstream server and
ask for a proper SSL certificate to be used. If that
cannot be attained, this option can be used to specify
the name (CommonName) that fetchmail expects on the
server certificate. A correctly configured server will
have this set to the hostname by which it is reached,
and by default fetchmail will expect as much. Use this
option when the CommonName is set to some other value,
to avoid the "Server CommonName mismatch" warning, and
only if the upstream server can't be made to use proper
certificates.
Beside that I think that the bug should be downgraded...
