Hello!

This was absolutely my fault, so it was a surprise situation for a couple 
minutes. The first I did is disabled backscatter on ForeFront, just forget to 
mention this.

Thanks! I've already did it.

Which behavior of assp do you expect?

ASSP not expects to get BATV-tagged mails from a local MTA - strictly not, if 
'DoBATV' is enabled (this is nonsense!) - it will possibly work, if 'DoBATV' is 
disabled, but this was never tested.

Solution - if BATV-tagging is wanted:

- switch off all BATV-tagging on local MTA's (Exchange Edge (with ForeFront) - 
in your case)
- configure the ASSP BATV options and enable 'DoBATV' (already done in your 
case)


recommendation:

Do not use BATV - used 'Do Message-ID Tagging and Validation (FBMTV) 
(DoMSGIDsig)'  instead.

________________________________



Hello!

I've started a new installation of ASSP an found strange behavior.
After I inserted ASSP to mailflow like this
Exchange - Exchange Edge (with ForeFront) - ASSP - Relay - Internet.
I've got two BATV sings (one from ForeFront and one from ASSP).
And LDAP query for local user fails if it wasn't in ldaplistdb.

I know, this isn't normal situation but I was a little surprised with behavior.

Publishing this info just to know how to deal with it.
