Hi, Net::SMTP does neither supports SSL nor IPv6.
git-send-mail does not use Net::SMTP directly for SSL support, but: - for direct connections (port 465) it uses Net::SMTP::SSL which just replaces the superclass if Net::SMTP with IO::Socket::SSL and thus implicitly supports IPv6 (because IO::Socket::SSL does) - for plain connections with SSL upgrade git-send-mail uses Net::SMTP for the initial connect and then does Net::SMTP::SSL->start_SSL (e.g. inherited from IO::Socket::SSL) to upgrade the socket to SSL. The problem here is that Net::SMTP does not support IPv6, but this should be solvable by using Net::INETGlue::INET_is_INET6 before loading Net::SMTP. But all these tricks are just workarounds for missing IPv6 and SSL support directly in the Net::SMTP, Net::FTP and Net::POP3. I therefore repeat my proposal from RT#93823 (no response yet) to add transparent support for IPv6 and SSL into these modules. By transparent I mean that the features are available if the necessary modules are installed (e.g. IO::Socket::SSL for SSL and IO::Socket::INET6 or IO::Socket::IP for IPv6), but that it works like before if they are not installed. I don't have these patches yet, but most of the necessary code is already there in Net::SSLGlue and Net::INET6Glue. Would you accept and incorporate such patches?
