git send-email was not authenticating properly when communicating over TLS with a server supporting only AUTH PLAIN and AUTH LOGIN. This is e.g. the standard server setup under debian with exim4 and probably everywhere where system accounts are used. The problem (only?) exists when libauthen-sasl-cyrus-perl (Authen::SASL::Cyrus) is installed. Importing Authen::SASL::Perl makes Authen::SASL use the perl implementation which works better. The solution is based on this forum thread: http://www.perlmonks.org/?node_id=904354.
