About:
This is a PHP class that attempts to validate a given e-mail address at three levels: matching the address against a RFC compliant regular expression, verifing the existence of the destination SMTP server by verifying the respective DNS MX record, and connecting to that server to see if the given address is accepted as a valid recipient. The class also features a debugging output option that lets you see the remote SMTP server connection and data exchange dialog to see the real cause why an apparently valid address may not be accepting messages.

No, it is just there have not been any more features to add or bugs to fix because the class does practically all it is needed.

[»] False negatives with this tool
by jganders - Dec 6th 2005 10:27:24

Not sure why, but I'm getting false negatives for all emails at a particular domain. Does the mail server at a given location have to be running sendmail for this class to work? Maybe Windows mailservers dont work? I dont know what platform is running the mailserver giving the false negatives. Can a sysadmin do something to hide an email server from the communication that this class utilizes?

The class just emulates the operation of a normal mail server.

Many mail servers are using grey listing now. The class was updated some time ago to consider of unknown validity the addresses served by servers that employ grey listing. I wonder if you are using an updated version of the class. If you are, can you tell me what e-mail addresses you are getting false positives?
