saving appengine mail from spam filters
- by Fh
One of my clients uses Trend Micro InterScan Messaging Security to protect their internal mail services.
Suddenly InterScan decided to filter out all messages coming from Google App Engine.
Unfortunately they haven't been able to whitelist the sender address as each e-mail gets a different one. For example, *3ckihSOVMMHlZHSL.JSMMHlZHSL.JS*@apphosting.bounces.google.com, with everything before the @ being variable.
Update I'm including this screenshot of how Interscan sees the incoming e-mail. Notice that all senders are different:
If I look into the e-mail headers, the apphosting domain appears inside the Return-Path field:
Return-Path: <36kSiSwYIBh0883XL3E7.5EH883XL3E7.5E@apphosting.bounces.google.com>
The "From" field looks ok. It says what I set it to say, but the spam filter only looks at the Return-Path.
My client sysadmin doesn't want to whitelist the whole apphosting domain, as it wouldn't be only whitelisting my application.
How could I bypass this e-mail filters if I can't get an unique sender?
Thanks,
