Hi all, &nbsp;I am having a heck of a problem with a client and need some suggestions. &nbsp;Client is running Exchange 2003 SP 2, single domain. &nbsp;Mail is filtered through a Barracuda Spam and Virus Firewall version 100. &nbsp;This past week we started to see one or two day delivery delays for any mail coming in from outside of the network. &nbsp;The delay is clearly (from headers) on the Barracuda appliance. &nbsp;No changes have been made, the delay just started happening seemingly out of nowhere. &nbsp;<br />
<br />
I have updated the firmware and all definitions files, no change. &nbsp;Also have rebooted to no avail. &nbsp;This is my first experience with the Barracuda device, any advice would be greatly appreciated!<br />

Barracuda spam firewall mail delay

Various techniques are used to prevent email spam (unsolicited bulk email). No technique is a complete solution to the spam problem, and each has trade-offs between incorrectly rejecting legitimate email (false positives) vs. not rejecting all spam (false negatives) - and the associated costs in time and effort. Anti-spam techniques can be broken into four broad categories: those that require actions by individuals, those that can be automated by email administrators, those that can be automated by email senders and those employed by researchers and law enforcement officials.

AntiSpam

Interactions between email servers and clients are governed by email protocols. The three most common email protocols are POP, IMAP and MAPI. Most email software operates under one of these (and many products support more than one).  The correct protocol must be selected, and correctly configured, if you want your email account to work.

Email Protocols

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.
