Address "Spammy" Outgoing Emails / Comply with X-Barracuda-Spam-Report Rules

[aaronskiba]

It turns out that indeed our Barracuda email security filters have blocked the messages with subject "Confirm your DMP Assistant account" that were sent from [email protected]. These messages matched some high-scoring proprietary Barracuda rules and ended up being dropped.

Here is the Barracuda spam report for a message received today:

I've opened a support case with Barracuda to try and find a solution, but I wanted to give you an update on what was going on. Perhaps there might be something that could be done from your side too to avoid those rules. Sending the message in plain text might help. Using the real name instead of email address in the "Welcome" sentence might help. If you must really send HTML-mail (why, oh, why?), at least compose it properly and definitely send the text/plain equivalent in a multipart/alternative message.
