Watermarking

[Paul Houselander (SME)]

Hi

 

Ive been trying to use the watermark feature all morning but with no
success, I can't seem to get it to add the watermark header?

 

I do use rulesets for most values but setting

 

Use Watermarking = yes

Add Watermark = yes

 

Seems to not do anything?

 

Im using Mailscanner 4.65.3

 

It does add a watermark if I send to my own domain i.e. from paul at domain.com
to paul at domain.com but if I send from paul at domain.com to paul at diffdom.com it
doesn't add the extra header?

 

I thought it might be to do with other rulesets as I generally don't scan
outbound e-mail

 

Scan Messages = %rules-dir%/scan.messages.rules

Virus Scanning = %rules-dir%/virus.scanning.rules

Spam Checks = %rules-dir%/spam.checks.rules

 

But ive set all these to do FromTo: now instead of just To: and still the
watermark doesn't get added?

 

Any ideals, I can see from the lists people are using it so know it works I
just must be missing something!

 

Cheers

Hi

 

I have a couple of questions regarding watermarking, I don't know if anyone
else is being hit the same but quite a few domains I look after have been
being hit by backscatter attacks over the last week.

 

I already reject all invalid recipients but these backscatters seem to be
targeting real aliases.

 

I want to use watermarks to filter out the bounces where the original
message did not come from my servers, but only on certain domains.

 

Do I just set

 

Use Watermarking = yes

 

Add Watermark = %rules-dir%/add.watermark.rules

 

add.watermark.rules

FromTo:               default no

From:    *@domain.com                yes

 

Check Watermarks With No Sender = %rules-dir%/check.watermarks.rules

 

check.watermarks.rules

FromTo:               default no

To:          *@domain.com                yes

 

Would this add a watermark for e-mail coming from *@domain.com and only
check watermarks for e-mail coming into *@domain.com - all other domains
would work as they currently do?

 

Is there any other caveats to watch out for? I seem to recall some
discussion about it misfiring on Microsoft delivery recipients?

 

Cheers

 

Paul
