Hi,

HeMan

I have configured tags (name+tag@domain.com) to go in to folders, and this is working fine. I have also configured an Address Rewriting rule to BCC all inbound mail to name+tag@domain.com so that I get a copy of all mail in my “tag” folder.
This does not work!
It does BCC the eMail to the name@domain.com mailbox, but it just appears in the root and not the sub folder based on the tag. The postfix log shows that it is forwarding it to the name+tag@name.com address, but it seems to ignore the tag in the case of Address Rewriting BCCs.
Should this be working as I describe, or am I misunderstanding something?

HeMan IIRC the tag function is running in Rspamd. So mails arriving from the Internet are handled, but your bcc rule and the resulting mail is sent internally and therefore not handled…

HeMan

Hmmm, I see. That makes sense… but is it something that someone might want to fix or re-work to make it possible? I don’t know enough about the inner workings of Mailcow and the flow between different parts to know if it would even be feasible?

But I was planning to use it to send different mailboxes to an archive mailbox with sub-folders for each mailbox in\out. Seems to me that if you are using address rewriting rules to catch mail from different mailboxes (which seems to be exactly what the address rewriting feature is written for) you might need some way of handling the different sources when they get to the archive, and + tags provide an obvious way of doing this.

Just a thought. If this is Rspamd dependent and those messages don’t go through it, they should be going through Sieve filtering. So maybe you’ll be able to mimic this behavior from there.

HeMan

OK, so I had a look in to Sieve and filters, but it seems this functionality is already implemented there, because there is a global Postfilter that, if I am reading it correctly (and this is the first time I have ever looked at Sieve syntax, so I might not be) already does the moving to sub folders based on the tag:

if allof (
  envelope :detail :matches "to" "*",
  header :contains "X-Moo-Tag" "YES"
  ) {
  set :lower :upperfirst "tag" "${1}";
  if mailboxexists "INBOX/${1}" {
    fileinto "INBOX/${1}";
  } else {
    fileinto :create "INBOX/${tag}";
  }
}

I didn’t add that, so I am guessing it is added by selecting the tag\subfolder option in the UI?

But if that’s the case, this isn’t firing for Address rewriting\BCCd eMails.

Those BBC does not have header :contains "X-Moo-Tag" "YES" so this does not apply for them if i’m not mistaken you need to work around this,…

require ["envelope", "subaddress", "variables", "fileinto", "mailbox"];

if allof (
  envelope :detail :matches "to" "*",
  not header :contains "X-Moo-Tag" "YES"
) {
  set :lower :upperfirst "tag" "${1}";
  if mailboxexists "INBOX/${tag}" {
    fileinto "INBOX/${tag}";
  } else {
    fileinto :create "INBOX/${tag}";
  }
}
