Limiting Connections

Phil Cook

My users connect to my mail server through 2 proxy servers. ASSP seems to be limiting the connections from these 2 servers. I thought it wasn't supposed to do that if you had the ip's listed under the isp setting. I only want to limit connections coming from the outside, never from the inside. Am I doing something wrong that is causing this to happen?

>ASSP seems

It would be easier, if the ASSP version is told.

There are so many bugfixes in 1.1.2 b1 & b2, that it would be needless
time consumption to search something which is already fixed.

What is in the log?

Besides that, you should consider to move ASSP to the front.  My
feeling is that  your proxys are producing a lot of bounce-mails.

Re: Limiting Connections

It shows connection from the ip then right away says Limiting Connections. What exactly do you mean by "move ASSP to the front"? I am running Merek Mail Server and ASSP on the same server. ASSP listens on port 25 and Merek on a different one.

But you are running proxies in front of it. So a lot of features of
ASSP will not work, because the incoming ip is always from your proxy.
ASSP is also build to answer with a smtp error in case of SPAM. In
your system the proxies will get the error and will send back a NDN.


"Limiting Connections" = total max of connections is reached. That has
nothing to do with IP-Nrs in the ISP-Field. Did you set a total max?
Then increase it.

Re: Limiting Connections

Phil Cook

No I'm not. The proxy servers are on the internal network. All email from the internet connects to ASSP. I also have an internal Exchange server but we have not moved everyone to this server yet. So some people who send mail go through ISA 2004 to the outside mail server and other people send to the exchange server, which then sends the email to the outside mail server. If the connection setting is too low it will limit connections from the proxy server and the exchange server. Too high and my cpu goes to 100%. My point is this, if I have the setting at 30, and I have 29 spammers connected, guess what will happen when 3 internal users try to send mail? Limiting connections.

May be I got your configuration wrong, because you mentioned that you
defined those "Proxies" in the ISP-Field. I would have exspected them
in "Accept all Mail" given your description.
