SBS2011 is running exchange 2010
If a user tries to send an email and the message contains certain words i.e. 'bugger'
The email is not received by intended recipient.
If the word is removed from the message it goes out fine.
I have checked hub transport rules under anti-spam section of Exchange Management Console and tried switching off recipient filtering, sender filtering, sender id and sender reputation but this did not help.
Note: content filtering under hub transport is disabled
We are using a mail filtering service (mailguard) but only for inbound
What changes can I make to reduce the threshold on what ever is blocking the mail going out?
How can I add specific words so they are allowed to form part of future emails?
