Hello,
a customer asked me if it is possible to block / deny senders which have numbers in their email adresses like (mike445@example.com) .
is it possible to build like a regex for that? is it possible to say if Sender has more than 2 Numbers or more than 3 numbers in his email adress?
Thank you very much

I haven't fully tested but you could try matching the sender with this regex in DLP incoming: .*[0-9][0-9]
Never heard of that, but it's NOT uncommon to have numbers in a email-address and specifically from a internet free email provider like gmail. Heck you will block a lot of emails if you actually did this ;)
I wonder if you have a incoming policy with a LDAP control to do this tho. This might be doable let's in a organization and address verifications for OUTBOUND but for incoming that would be strange approach? But typically ldap is done for recipient verification and to set specific receipient AS/AV profiles and controls from experience.

Hello,
now we have the Problem that Emails that will be signed for BATV like prvs=0091694b28=sn@example.com will be blocked because of that Regex :)
how should the Regex look like if it should match only this Criteria.
All Letters .(dot) numbers @ domain for example xyz.778@example.com
is it possible ?
Thank you
