Hi,
(FWIW I'm the current maintainer for signing-party and upstream for
caff(1), and I'll attend DebConf.)

caff doesn't send out mail on its own, it leaves the job to
Mail::Mailer(3pm), as mentioned in the manpage. AFAIK the ‘smtps’
method calls Net::SMTP::SSL and Mail::Mailer doesn't interface with
Net::SMTPS.
Net::SMTP (which is a core module) can do SMTP over SSL (thereby
deprecating Net::SMTP::SSL) and also issue STARTTLS since v1.28. For
SMTP over SSL, the following $CONFIG{'mailer-send'} should work:
[ 'smtp'
, Server => 'smtp.example.net'
, SSL => 1
, Auth => ['username', 'password']
]
And since the configuration file is just perl code, one can spawn a
command to retrieve the password instead.
Here is another example, with a custom EHLO keyword, envelope sender
address, port [0], and custom SSL options incl. client cert
authentication [1].
[ 'smtp'
, Server => 'smtp0.example.net'
, SSL => 1
, SSL_verifycn_name => 'smtp.example.net' # hostname verification
, SSL_hostname => 'smtp.example.net' # SNI
, SSL_use_cert => 1
, SSL_cert_file => $ENV{HOME}.'/.mail/smtp.crt'
, SSL_key_file => $ENV{HOME}.'/.mail/smtp.key'
, Hello => 'hi.there.org'
, From => 'user@example.net'
, Port => 465
]
In principle replacing ‘SSL => 1’ with ‘STARTTLS => 1’ would work for
STARTTLS, but unfortunately Mail::Mailer doesn't expose this yet. I
guess I should file a bug as it's really a 3 lines patch :-)
Cheers,
