Tagging not working for BCC Map Destination

i_like_beef

Hi there!
I am using a BCC recipient map to forward all incoming mails of a distinct mailbox (sender@mydomain.com) to another one (recipient@mydomain.com). The BCC recipient address is a tagged address (recipient+xyz@mydomain.com), and the receiving mailbox has been set to show the tagging in the subject of the mail.
The tagging works fine as long as I send mails directly to the tagged mail address. For the ones that are forwarded through the BCC map, the tagging doesn’t work.
Any ideas, how I can get that working?

Thanks and BR!

Alright, instead of using a BCC Map, I have solved this by using a Sieve Prefilter on the mailbox that should get it’s mail forwarded:

redirect "recipient+Xyz@mydomain.com";
# Keep after redirecting:
keep;

That works as expected 🙂
Moreover, this way I can even add multiple recipients with tagging and it works just fine.

BR!
