   Sorry for top-posting and HTML email (just painful webmail now).

   To force sendmail relay mailer to connect to your smart host on port 465, add:

   define(`RELAY_MAILER_ARGS', `TCP $h 465')dnl

   after define(`SMART_HOST', .....)

   in your .mc file.

   But, as far as I can remember, sendmail doesn't support smtps, just STARTTLS. Years ago, I used to setup stunnel to do smtps instead, and left sendmail connection settings untouched. Can't say what's the current state of things, luckly I don't need smtps today.

   Bye,
