Oh yes, you're right. A word boundary is a better choice, indeed.

It's a part of my acl_smtp_data (now with the better \b escapes):

warn
message = X-ACL-Warn: Message with bad term (= $regex_match_string).
regex = \n(?i)\bviagra\b\N : \N(?i)\bcialis\b\N : \N(?i)\btadalafil\b\N
logwrite = :main: MSG_D04_REGEX1 (= $regex_match_string).

Yes, now it does work! (I will "repair" the other terms es well).

The X-ACL-Warn header was not added to the message.

Thanks a lot for your help
