After a fit of similar frustration I wrote a short article on how to validate e-mail addresses programmatically. It's half serious and half entertainment, but it may be worth looking at.
Someone in one of the comments below the article mentioned that O'Reilly's 'Mastering Regular Expressions' has a RegEx that can be used that is 'pretty good'. According to the comment: "The most comprehensive version of this expression that I have seen is printed in Mastering Regular Expressions from O'Reilly. It is on page 316 and weighs in at 6,598 bytes long." See "How to validate an e-mail address" - http://www.oreillynet.com/pub/wlg/2379 |---------+-----------------------------> | | | | | "Noel J.

I looked earlier, and I do not see anything that permits a localpart with no domain, except for <postmaster>. A bug in the code, which certainly exists, is that it should check the position before trying to access the @, so that it can report the error that it wants to report. --- Noel --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------------- This e-mail message (including attachments, if any) is intended for the use of the individual or entity to which it is addressed and may contain information that is privileged, proprietary , confidential and exempt from disclosure.
