If the mail server (MTA) doesn't like your email addressing format, it simply won't send the message. If it gets through, it may fail at the recipient's server. The From: address is not typically processed by the mail servers. For this reason, the email client program (MUA) being able to process the real <email> format is more important. It is a legal addressing format. My suggestion is to not use it in the To: address (and perhaps not the CC: and BCC:). James
