Those are SIMS internal status codes, and are not dumented anywhere that I've seen.Intellectual curiosity-type question: I think I've figured out most of the error codes in SIMS, but the following has me a bit puzzled. I believe what I have here is a spammer [ [EMAIL PROTECTED] ] testing for open relays by trying to relay to itself. SIMS defeated him, no problem!Question #1: what is the meaning of the *Status codes? Does SIMS generate these or are they from OT? I see status 34, 22, 21, 25, 26, 23, 29, 1, and 2 within the transaction.
Question #2: I was under the impression that SMTP used port 110 and POP3 uses port 25.
Other way around.
Each end of any TCP connection has an IP address and port number. Your end is on the SMTP port, 25. The other end is almost always going to use some arbitrarily chosen high port number, such as 4558. Typically a firewall set to support internal servers lets through traffic aimed at the server's port number (typically a low-numbered port, as those are the ports which have been assigned to most common services) from any port on a remote IP address. Both ends are not required to use the standard port reserved for a protocol, and on many OS's that wouldn't be possible since the low ports are restricted to use by 'root' on anything Unix-like.But our spammer friend comes over on port 4558. How did he get through the firewall (IPNR on Mac), which has does not have this port enabled?
