Re: Mail problem reason: 550 5.1.1

Don't use uppercase letters in the username. This field contains no uppercase characters, and must not be more than eight characters in length.
If You really need it, set the flag "u" in "Mlocal, F=..u" in sendmail.cf


u - Uppercase should be preserved in user names for this mailer.

Regards,
Sergejs
