Dear folks, I'm just moving our mailing from one server to another. Up to now we used Postfix version 2.7.1 with Cyrus imap server. Local delivery goes via LMTP.
We have dozens of shared folders. /etc/aliases contains several lines like this: foo: user1, user2, user3, +bar So incoming mails addressed to <f...@example.com> were delivered to three users and the shared folder "bar". Now the new 2.11.3 Postfix refuses delivery to shared folders and assumes that "+bar" is a local user name. Mails are deferred with status "user lookup error". After searching Google half a day I found that the alias file syntax we used so far is not supported at all. At least it is undocumented. (I just inherited these aliases some 8 years ago. :-) Maybe this was just a bug or side effect that was fixed since 2.7.1. I wonder what is the official and bullet-proof way of dropping mails into shared folders? Any hint will be appreciated. Gabor
