Actually it was probably a 450 error with a 4.1.2 Enhanced Mail System Status (for humans) of what is going on. > Since I was replying to a known sender, I neither mistyped > nor missent. > I called my ISP to find out what error 4.1.2 was.

He should have figured out that it was a 450 error: 450 Requested mail action not taken: mailbox unavailable > So, did seamonkey generate this error code or did it get it > from my isp and patch it into the error window?

That is because '4' error codes are Persistent Transient Failures.

Thanks. This might help: http://www.greenend.org.uk/rjk/2000/05/21/smtp-replies.html and particularly: http://www.rfc-editor.org/rfc/rfc1893.txt 4.X.X Persistent Transient Failure A persistent transient failure is one in which the message as sent is valid, but some temporary event prevents the successful sending of the message. Sending in the future may be successful. X.1.X Addressing Status The address status reports on the originator or destination address. It may include address syntax or validity. These errors can generally be corrected by the sender and retried. X.1.2 Bad destination system address The destination system specified in the address does not exist or is incapable of accepting mail. For Internet mail names, this means the address portion to the right of the "@" is invalid for mail. This codes is only useful for permanent failures. _______________________________________________ support-seamonkey mailing list [email protected] https://lists.mozilla.org/listinfo/support-seamonkey
