anti spam exchange tag [spam] all email from antispam filter online
Hi,
I have a problem with some exchange servers 2010.
I have an external anti spam filter (online) to point my MX Record.
When an email come to the antispam filter. Every mail was tagged [spam] in the object email but it's the exchange server who tagg [spam] not our antispam filter.
If I disable all option's antispam in exchange manager.. I have always [spam] in object..
But if I point my MX directly to my exchange server, the mail come correctly to the mailbox without [spam].
Some people have an idea to resolve this problem.
For informations all work fine before last week.
Many thanks.
