I dont understand why both XMPP and SMTP decided to go the route of deprecating tls-wrapped options and instead only do STARTTLS. This seems like a wrong approach. Even though 465 was deprecated by the IANA a long time ago, its still widely used for wrapped TLS. In fact, I use it for that purpose because I dont want to support a downgrade attack STARTTLS option. _______________________________________________ Ach mailing list [email protected] http://lists.cert.at/cgi-bin/mailman/listinfo/ach
