Well, pretty much as the thread title says, it seems that our new firewall is blocking outgoing POP email. Incoming POP mail works fine. Also both incoming and outgoing IMAP email works fine. If I try to send an email from my POP account I get the follwing error email:

Subject: Undeliverable [sent message subject]
Message: Your message did not reach some or all of the intended recipients.
[subject, sent date and time, list of recipients]

message . . . another weird thing is that it comes in my Archive Folders - Inbox rather than my Personal Folders (where my POP mail is set to filter to).

We recently removed our SBS2003 server(s) (we just use a Network Attached Storage device for User authentication) and Watchguard Firebox to simplify our life. In it's place we installed the Netgear ProSafe FSV336G Dual WAN firewall (we're just using the single WAN2). The computer that I'm using is an Apple MacBook Pro running Windows Vista Ultimate.

The documentation from Netgear shall we say is lacking. And help would be much appreciated. Thanks in advance!
