No new tickets from external email

[netjess]

Hello All,

I would like to limit email from external sources but not cut it off altogether.
I have found it nice to be able to communicate with external recipients to keep certain communication inside the ticket, however I would like to keep new tickets from being generated by inbound messages from sources outside of our email domain.

I have looked at PostMaster Filter but I am unsure of what to use to accomplish my goal described above.

In short: allow replies from external domain but ignore new messages from external domain. I could also see it being beneficial if there was some way white list particular email addresses as exceptions to the rule.

Thanks.

Something like this might work if there is a way to state "all except @mydomain.com".
Edit Config Settings in Ticket -> Core::PostMaster
PostMaster::PreFilterModule###3-NewTicketReject

I also found this post from a few years back but would like to not have to manage changes across updates.

Seems legit. So if you don't match anything, it doesn't filter... so then match @mydomain and SET X-OTRS-Ignore: 0 in PostMasterFilter after enabling the pre filter.

crythias,
What I would like it to do is "not ignore" if it is from @mydomain but ignore if it is from any other domain.

Not sure how good you are with regex (it gives me a headache).
^(?!@mydomain$).*

Would that allow a match for everything but @mydomain?
example:
block @1mydomain.net
block @my.domain.net
block @gmail.com
allow @mydomain
allow @mydomain.net
allow @mydomain.com

Thanks for your help.
Jesse.

Well, I tried it and it blocked everything.

Back to the drawing board.

In short: allow replies from external domain but ignore new messages from external domain.

For a reply the queue disposition (X-OTRS-Queue) of a postmaster filter is not active.

Therefore it should be sufficient to create a simple postmaster filter:
Check email header:: From
Negate: Checked
Look for value: @mydomain\.example$
Set email header: X-OTRS-Queue
Set value: Not_Wanted

To the queue Not_Wanted you could attach an appropriate auto response or delete the tickets automatically.

Postmaster matches after pre-filter. Block first then unblock.

schulmann, So the "Negate" check box designates a negative value (everything but the value)? I thought that it meant to turn off that part of the filter.
Thanks.

Thank you.
