Not a problem.

No one's said anything about a firewall *on* the server. There are a number of routers and firewalls in between your clients and your server, and it's possible that one of them is broken. It's also possible that some client software is broken.

I know. That's why i asked about any known problems with Panda AV/Firewall.

I'm not aware of any.

The first step you should take to figure it out is, as I said before, to get a list of all of the courierpop3login processes running on your system. Then use 'netstat -tnp' to determine whether those connections are open from just one host, or from many. Once you know who started the connections, then you'll have somewhere to look to find out why it's happening.

Of course that was the first i did. :)

I don't recall your having said so.

There is only one host which is using our pop3 server. 7 clients on a shared internet connection.

Well, i guess the problem ist the broken Panda software.

I don't think you've established that quite yet. The most likely culprit is the host sharing the connections for your clients, I would expect. What kind of host is providing the connection sharing to your 7 clients? It may have a way to list open connections. If so, getting that list would go a long way to determining where the problem is.

If not, I'd make an effort to get the OS or firmware on that host updated to the latest version.
