Ticketing Systems' Alias Email Creates User

Pietro_Aretino · Apr 19, 2018

I have osTicket setup running with Postfix/SMTP; it has local accounts e.g. oshelpdesk, osticket, osalerts etc. setup who authenticate to the SMTP server to send and receive email. Cool, no problem.However, we have a mail exchange server where the SMTP relays off of. It has aliases configured to send to the above email addresses.For example,ticket@mydomain.com -----> osticket@sub.mydomain.comhelpdesk@mydomain.com ----> oshelpdesk@sub.mydomain.comAnd it works great, no problem.However it constantly generates users because of this. So in our users list we have all these non-real alias users.Is there anyway to prevent this from happening? Its not a huge deal but just curious if anyone has found a work around or if theres a feature im not aware of.

How is postfix configured exactly? That sounds like it's not rewriting but adding a header, so all those aliases would be cc'd on each ticket

Postfix is just configured to authenticate SMTP local user accounts, and send and receive via SMTP. It then relays everything to our exchange server.The thing is, that the Exchange server is setup to forward mail from our main-domain to the osTicket subdomain.SoInternet ---> Exchange Server (email@mydomain.com) ---> osTicket/Postfix (osemail@sub.mydomain.com)
