HELLO!
If I write a mail using the SMTP-PORT of my mail-server (e.g. smtp.mail.yahoo.com) and I send the mail to [email protected], I think my mail-server connects to port 25 (SMTP) of "somewhere.com". But often "somewhere.com" does not support SMTP, but the mail reaches the correct recipient at "somewhere.com". How does "smtp.mail.yahoo.com" transfer the mail?!?
