When forwarding messages using Roundcube filters, sender is different than when manually forwarding

1

Hi, first time poster.
We have multiple email accounts set up on MIAB, for each branch of our company.
BranchA@domain.com
BranchB@domain.com
etc…

We want to forward every message received by these addresses to a main processing address (BatchProcessing@domain) so we can batch process them, but we need to have BranchA@domain be the “sender” of the email when it arrives, so we can differentiate which branch address the email was originally sent to.

When I manually forward a message in the inbox, this is the case, and we are able to get the result we want: The BatchProcessing@domain inbox shows BranchA@domain as the sender.

However, when I set up automated forwarding in roundcube, BatchProcessing@domain inbox shows the email’s original sender, not the BranchA@domain.

Is there a way to get the address doing the automatic forwarding to show up as the sender? I looked around the forum and it seems that people want the opposite, or something different.

Thanks for the help.

I had similar problem with small different.

I wanted also to to have what called BCC “blind carbon copy” from mail to one general mail (I’m not sure if this what you are looking for ).

for example : emailA@domain.tld and emailB@domain.tld receive emails from unknown@domain.tdl
you want copy of incoming mails to all users to be sent to one general email right ?

in /etc/postfix/main.cf you can add : always_bcc=targetMail@domain.tld
this will make copy of all incoming mails in ‘targetMail@domain.tld’ then you can filter mails as you wish inside ‘targetMail@domain.tld’

Note: I programmed small Nodejs SMTP software to read incoming mails from targetMail@domain.tld to filter them or notify me what mail to which user is came.

Hope that will help you.

I was able to “solve” the issue by having Thunderbird filters do the actual forwarding.
By using /etc/postfix/generic I was able to replace specific senders with specific forwarding addresses, but the issue with /etc/postfix/generic, is I don’t know the correct regexp for changing the original sender to the original recipient. Since no easy answer was forthcoming there, and we were on a deadline, Thunderbird had to suffice.
