how to work with url in receiver mail adapter

hi,

iam trying to implement simple file to mail scenario.

I've got stuck with mail adapter configuration.The transport protocol iam using on receiver end is the SMTP protocol.

i have mentioned the url as smtp://abc.xyz.com:25.Then iam getting an error saying that invalid syntax error.

Is this the correct approach?kindly suggest.

All helpful answers are appreciated.

Thanks & Regards

Madhu
