Well my new firewall hasn't come in so I'm still stuck with this Cisco Pix 506E firewall.<br />
<br />
I am having POP3 problems and the support staff is telling me it's my firewall.<br />
<br />
<br />
I'm hosting POP3, if I TURN OFF SMTP Authentication on my mail server, my clients can Send/Recieve email no problem.<br />
<br />
If I TURN ON SMTP Authentiation on my mail server, my clients can recieve mail but CAN NOT send mail.<br />
<br />
YES, the email clients are configured with user/pass for server SMTP Authentication. I've tested myself.<br />
<br />
Support staff says it's something to do with my firewall because I gave them access to the mail server and a test account.<br />
<br />
So what do I need to open up besides 110?

SMTP Authentication Port on Cisco PIX?

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.

Software Firewalls

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).
