Address is with a comma

[dpinkston]

Anyone run into an issue sending an e-mail to someone with a comma in their e-mail address? I am getting 5.1.1 unknown user reply from my local e-mail server.

are you sure its correct? A comma is an invalid character in an smtp address and would normally be used as a delimiter.

Yup, works fine when sent from my gmail account.

As mikethebike said, the comma is a delimiter so it shouldn't be accepted in an email address.
