Strange Postfix from address when forwarding mail

Background: I have a users domain (aaaa.com) on a dedicated IP. User has a webform that emails info to user@aaaa.com. This worked fine on a different server.

When the mail hits "user@aaa.com" mail box we have it setup to put a copy of mail in mailbox for "user@aaa.com" and also forward mail to "allmail@aaa.com."

The customer then pops the mail from allmail@aaa.com and processes with a script.

Here is where the problem comes in, the header information for the email in user@aaa.com and also allmail@aaa.com has a weird from address. From: john doe <johndoe@hotmail.com>, ")"@s3.aaaa.com Note the: ")"@s3.aaaa.com

Any suggestions on to solve this problem would be much appreciated. I checked the following files and didn't see anything obviously wrong: /etc/aliases /etc/postfix/virtual /etc/postfix/master.cf /etc/postfix/main.cf /etc/procmailrc

Sample header follows, Thanks, Roger

Note: domain bbbb.com is an alias for aaaa.com so user1@aaaa.com == user1@bbbb.com
