Kind of. 'Read before send' is a method of temporarily authenticating IP addresses so that SIMS will allow SMTP relays from them (this method is not unique to SIMS). The way it works is that when a user logs in via POP to retrieve mail, SIMS temporarily adds the user's IP address to the client hosts list for whatever time period has been specified in the settings. This solves the problem with a static clients list that mobile users can't relay through the server if they've dialed up to an IP address that's not in the list.
That makes sense. DUH. ;^)
So now you lost me.No. It doesn't affect the ability to log in via POP, it simply allows SMTP sessions to be indirectly authenticated by a POP login immediately prior to the SMTP connection. POP sessions are always authenticated, so it's not necessary to restrict them in the same way that SMTP relays are restricted.
Can I retract my earlier remark?
Chris <-------------- SUPER-DUPER Idiot when it comes to SIMS
OK, I feel better.
So, that said, Christopher, does that mean that the POP module is passing the username and password to the SMTP module for TEMPORARY use at that point?
And if so, would having this setting at "never" prevent ANY SMTP from the outside (which is I guess what I'm getting from your explanation)
Is that correct?
Umm, Sorry.Uh, not sure exactly what you're asking. POP is a protocol for retrieving mail. It requires username/password authentication to establish a session.
Again, I'm not a veteran with mail servers or SIMS, but I've at least got it setup and working thanks to you all and the SIMS docs. ;^)
I realize that POP answers on 110. What I wasn't for sure was the actual method (username/PW, IP, etc) and if there was more than one for POP authentication. :^)No. SIMS answers connections on port 110 as POP3 connections, and expects the remote host to speak POP. Once the connection has been successfully authenticated with a valid username and password, the user has access to the mailbox associated with the username.
SIMS doesn't care what the remote IP address is for POP connections, since POP sessions are always authenticated by a username/password.
That's what I thought, but wasn't sure. Thanks for all the info, Christopher. :^) Chris ############################################################# This message is sent to you because you are subscribed to the mailing list <[EMAIL PROTECTED]>.
