One E-Mail should create one Ticket.
I’m not shure, but I think I’ve found a race condition where Zammad generates two Tickets from one E-Mail. The following happens sometimes:
Zammad fetches an E-Mail and while it processes this E-Mail the same E-Mail is fetched again and a second Ticket is created. In the production.log I see two entries:
I, [2021-01-19T11:20:08.545375 #15690-46998324254920] INFO – : Process email with msgid ‘firstname.lastname@example.org’
I, [2021-01-19T11:20:16.170992 #1420-47250214050120] INFO – : Process email with msgid ‘email@example.com’
Probably the mailserver is to blame, because it should not provide the already fetched mail. But I’m not shure if the behavior of Zammad is correct either.
Steps to reproduce the behavior:
As every race condition, very dificult to reproduce. But I can provide Logfiles if needed.
