Re: SMTP and Port 25

I don't know if you can do it with Indy but you can use port 995 for POP3
using SSL with Exchange.
But unfortunately there is no secure SMTP port.
You could use IMAP with SSL instead though.

According to Microsoft, they support SSL and SASL (NTLM) as of Exchange
Server 5.5. They also claim to support TLS in Exchange 2007. I can't claim
any real experience with either, but they're listing them as "Features".

Not only do they not specify a secure port for SMTP, but RFC 2821 doesn't
even mention the standard port number 25. Funny.
