Postfix and netinfo == recipient_delimiter won’t work?

[Pascal]

I tried to make use of Mail Address Extensions and set (as per default) the recipient delimiter to ‘+’:

postconf recipient_delimiter
recipient_delimiter = +

Unfortunately this does not make things work 🙁

I suspect this is because of the combination of postfix and netinfo — but just a guess…

Has anybody had more success with this?

BTW: It is indeed *not* Postfix, as it will forward mail with recipient delimiters to Mailman without problems. Which is very handy if you intend to upgrade Mailman from 2.1.2 to 2.1.5.

In another attempt — and because I thought it could be a deliver-related problem — I set:

mailbox_transport = lmtp:unix:/var/imap/socket/lmtp

Postfix seems to talk directly to Cyrus via LMTP now, bypassing the deliver program. Though this does work as usual, it does not enable address extensions in Cyrus either… 🙁

Anyone has any other ideas?

I did finally find the answer. In our case it was Postfix that was rejecting the e-mail because it didn’t recognize the user “postuser+info” or whatever.

To solve this, I created a file in /etc/postfix named local_recipients_regexp with this regular expression: /^[email protected]/i OK and added this file to the local_recipient_maps in Postfix. See below:

postconf local_recipient_maps
local_recipient_maps = proxy:unix:passwd.byname regexp:/etc/postfix/local_recipients_regexp $alias_maps

This tells postfix that addresses with a + in them can be accepted. Once Postfix accepted the e-mails, they were delivered to the shared folders correctly. Note that I had to also set postuser in /etc/imapd.conf.
