Hi James

Unfortunately in theory all mail servers should use the relevant status error codes, but in reality this is not the case, and hence why I am looking for a library of algorithms / signatures to help identify these e-mails i.e. Challenge/Repsonse e-mails, out of office e-mails, mailbox full etc.
Refer to my recent post as I have found a number of products which include this functionality.

Cheers.
Matt
