Postmaster PreFilter VS Postmaster Filters

[jff]

Hello Everyone,

I've been strugling with the following:

ON Ticket -> Core::PostMaster I have enabled the option
PostMaster::PreFilterModule###3-NewTicketReject

NOTE: There is a X-OTRS-Ignore set if there is no ticket on the subject line.

This works beautifully when there is a valid ticket number on subject line independent of the FROM of the e-mai.

But I have 2 main accounts that should be able to open tickets:

monitor@company.com
itsm@company.com

So I should receive a device alarm e-mail on itsm@company.com then I will regex my way to open the ticket with the right information but the problem is that I am falling on that PRE filter and since this "alarm" e-mail has no ticket in it it is being ignored right away.

Is there a way I can enable follow-ups on ticket IF there is the TT# on subject line while also being able to open ticket with a determined account?

I hope I could explain myself in this.

Thank you.
