Using one e-mail addresse as sender address for multiple queues

[aph]

I have a central queue where a ticket is created from a fetched e-mail. Depending on which department should handle it, the ticket is moved to the relevant queue. When the agents reply a customer from the relevant queue I would like to use as the sender e-mail address, the same address as that of the central queue. I would like to know whether it is possible to use one e-mail address as the sender address for multiple Queues.

I had this doubt because when adding a system address, OTRS asks to select a queue.

No problem there.

The queue value in System Address is used when you have one mailbox with aliases. Then you would select "based on To: field" in the Postmaster Mail Account admin screen and OTRS uses the values you select in the System Address admin screen to distribute the tickets.

note that tickets don't change queues based upon followup email address unless PostMasterFilter tells them to.

I didn't quite get that with aliases. Can you elaborate a bit more.
So if I get you right, I can use aliases of the same mailbox. So I can have one mailbox for example abc-support@mycompany.com. I can the have two aliases xyz-support@mycompany.com and pqr-support@mycompany.com. In PostMaster Mail Accounts I would add the mailbox address (abc-support) with the password and host and select dispatching my e-mail to field. Under system addresses (Email setting -> Email addresses) I can add the two aliases xyz-support and pqr-support and select the queues I want the e-mails to be delivered to. Do I get you right?
Another question that comes to my mind: Consider the following scenario A ticket was created from email sent to xyz-support in queue1 (which uses xyz-support as sender email address). An agent replies to the customer and moves the ticket to queue 2.
Now when the customer replies will the reply land in queue 1 as I have configured dispatching by email to field or will it land in queue 2 based on the ticket number?

Yes.

tickets don't change queues based upon followup email address unless PostMasterFilter tells them to.

This means that all tickets keep all settings on followup unless X-OTRS-FollowUp-field is specified.
X-OTRS-Queue is for tickets without ticket numbers
X-OTRS-FollowUp-Queue is for tickets with ticket numbers

No, dispatch by To does not override followup. It does not set X-OTRS-FollowUp-Queue.
All followups that otrs receives stays in the current ticket's queue, no matter how the ticket arrived originally, and no matter what the sender address is of the queue.
