Explicit SSL SMTP: uses two ports, 25(fixed) to start connection then switches(via STARTTLS) to submission port 587(variable) for SSL encrypted channel communication (Reg: RFC 3207)

Support for Explicit SSL SMTP - moved from development thread (this would be very helpful for development work) If hMailServer would add TLS authentication then I could use a local copy of it to do sendmail (relayed through GMAIL SMTP) from my local development webserver. I do manage to send personal emails via GMAIL SMTP with my local copy of Thunderbird but it needs TLS authentication. The largest provider in town has it's main SMTP server MISCONFIGURED (wrong HELO machine name!) and after a week of talking to top managers asking them to take the 30 seconds required fix it, it was still fruitless. I've tried several Moscow ISP's and all of them are too lazy to get themselves un-blacklisted. If you believe that this failure is in error, please contact the intended recipient via alternate means.' 'RECEIVED: 554 Your access to this mail system has been rejected due to the sending MTA's poor reputation. I'm in an 'internet hellhole' (Moscow!) and it's very hard to get emails out (many email servers around the globe reject mail coming from Moscow subnets due to 'bad reputation').

I'd really like to see TLS authentication for SMTP.
