hwo to use TidSMTP when mailserver has no smtp but ip only
===

i developed an application that sends email messages using indy (`idSMTP` + SSL).
The `idSMTP` properties I expose to the user are simply:
smtp
user
password

anyway in some cases the users have an internal mailsender that doesn't have an smtp address, but simply an internal ip (like 192.168.48.63) and no user and no password.

i tried to set ip = to smtp but it doesn't work.

Could you sugeest a solution?
