Postfix transport_map equivalent

[blacs30]

Firstly: thanks for this wonderful creation, a dream for all the self hosters.

I am currently planning the migration to this mail-server.

I came across one thing where I am not sure how to convert the config.

I have an archiving smtp server listening on 127.0.0.1:2525.

All emails should be bcc'd to it,
In postifx i do it with always_bcc in stalwart smtp i think the session.rcpt would be the place to add a sieve script with an editheader bcc [email protected] entry.

The part where i don't know how it would work here is how i can convert the transport_map.

Right now i have something like this

/etc/postfix/main.tf
transport_maps = hash:/etc/postfix/transport

/etc/postfix/transport

piler.local smtp:127.0.0.1:2525

Do you have an idea?

Hi,

Yes, this could be done using a Sieve script at the DATA stage. If your mail server does not have a domain name configured (i.e., it accepts and archives messages for every massage it receives), then you'll have to create a mock email address and route a copy of the messages to it.

For example:

[queue.outbound]
next-hop = [ { if = "rcpt-domain", eq =  "piler.local", then = "archive" }, 
             { else = false } ]

[remote."archive"]
address = "localhost"
port = 2525
protocol = "smtp"
concurrency = 10
timeout = "1m"

[remote."archive".tls]
implicit = false
allow-invalid-certs = true

[session.data]
script = "archive-copy"

[sieve.scripts]
archive-copy = '''
require "redirect";

redirect "[email protected]";
keep;
'''

Nice, that looks so clean. Will try it out. Thanks a lot for the prompt help!

for outgoing mails with additional bcc addresses, these bcc addresses are not shown in the mail stored in [email protected]. @mdecimus is there a way to include bcc addresses in the redirected mails or redirect the true original mail? This would be crucial for auditing or compliance when information leave the institution via bcc and cannot be traced back.

Bcc (blind carbon copy) recipients are supposed to be hidden in the message headers. If you would like the recipients to appear in the headers, you need to add them using Sieve.
