Out of office replies and Undeliverables

Hi.
For some reason, undeliverable messages received from lots of server as well as Out of office replies shows up in EFA with no sender. Then EFA flags them as spam. Reason given is "(no watermark or sender address)"
What can I do to allow messages with no sender to be received ?
BTW. I'm really impressed by the performance of the product. Cheers to you all !

We have heard of this problem before, but never been able to re-produce it to see where the issue is.
Are you able to send a part of the mail log from one of the failing messages?
Also the full message e-mail that is marked as spam could be usefull.

I don't have the log, but I do i have one message.
Where would I send it ?

Actually, I may have your solution...
Try modifying the following line in /etc/MailScanner/MailScanner.conf as follows:
Code: Select all
Treat Invalid Watermarks With No Sender as Spam = 2
These type of emails seem to get the watermark stripped from them on the remote side with some types of email servers. Setting this value below your spam threshold will treat these emails with suspicion but not automatically flag them as spam unless other triggers occur.
Don't forget to restart mailscanner...

I have the same problem with release 3.0.0.7
I have checked setting "Treat Invalid Watermarks With No Sender as Spam = 2" but it is the default setting.
Is there an other work arround to solve this problem?

You could completely disable this setting and see what happens
Code: Select all
Treat Invalid Watermarks With No Sender as Spam = 0

Hi shawniverson,
I give it a try and let you know the result.
Meanwhile, I also searched the internet for a solution and I've found several advices to set "Use Watermarking = no"

Yes, both settings would have the same effect

Hi shawniverson,
I have changed the setting 'Treat Invalid Watermarks With No Sender as Spam = 2' to 0 and now it's all working well!
Thanx!
