I get the following in entourage 2008 when sending out an email:
5.1.2 or other punctuation after the recipient's email address. 4sm2467811ywd.29
The error also says mail couldnt be sent. But the mail does get sent.

I got this error since changing my signature. I put links in for my email and website....any idea how to make it go away...I dont want to clear errors every time I send an email...
