There may be a SMTP class to help you do it, or you can do it manually but here is a quick process. Look up the MX for thedomain.com. maybe use checkdnsrr(). If not found then it is bad, if found connect and issue the following SMTP commands: MAIL FROM: [EMAIL PROTECTED] 250 ok RCPT TO: [EMAIL PROTECTED] 550 sorry, no mailbox here by that name. (#5.7.17) Optimally you want to see: 250 ok You could also see: 553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1) This would mean that there is an MX record for thedomain.com pointing to this server but this server isn't configured to accept mail for this domain. -Shawn -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
