Question : PIX 501 firewall and Mdaemon mail server

how do I get my mdaemon mail server to correctly work under a PIX 501 firewall??

I have port 110 tcp&udb and 25 udp/tcp open

but it seems connections are getting blocked when sending mail to the server...  I'm checking on mdaemon and it seems to be stuck, connections are using ports 2000+

do i need to open a certain port range on the PIX 501 for this????

The "fixup 25" is problematic with a lot of mail servers - it tries to analyze the conversation and block anything 'non-standard'..
, and the default is to use ESMTP and fallback to SMTP on those servers that support it, you should be able to leave that option in place.
There's two issues at work here, the mail server's dialogue with the other server.
Do you have a DNS record in place for your public IP address?
and a reverse dns entry (PTR record)?
Can you telnet to port 25 from the mailserver to the machine you want to connect to?
