Dovecot 1.2.11, using postfixAdmin 2.3 to manage, basically using the postfixadmin schema and sql queries during install.
If I set a forward for an account to go to a remote email address, no dupes.
If I set a forward for an account to go to an email address on the same system, I get a dupe in the inbox of the second address.
So if account1@domain.com has account2@domain.com as a forward, account2@ receives two copies of the same message, completely identical, same message IDs, same md5 sum. If I add account3@ into the mix, account3@ will also receive two copies of each message.
I will also get a duplicate if I forward mail to account@anotherdomain.com, where anotherdomain.com is also hosted on the same system.
account1@domain.com receives one copy.
Here is the Dovecot log:
Jan 18 17:24:40 deliver(account2@domain.com): Info: msgid=<4D361323.3040000@srvr.net>: saved mail to INBOX Jan 18 17:24:40 deliver(account1@domain.com): Info: msgid=<4D361323.3040000@srvr.net>: saved mail to INBOX Jan 18 17:24:40 deliver(account2@domain.com): Info: msgid=<4D361323.3040000@srvr.net>: saved mail to INBOX
Postfix logs only show one delivery for each message, and since the headers aren't changed at all, I think the lda is at fault here.
This is the entry for the account in the 'alias' table
======================== mysql> select * from alias where address='account1@domain.com'; +-----------------------+----------------------------------------+------------+---------------------+---------------------+--------+ | address | goto | domain | created | modified | active | +-----------------------+----------------------------------------+------------+---------------------+---------------------+--------+ | account1@domain.com | account1@domain.com,account2@domain.com | nyinet.com | 2010-11-28 18:07:40 | 2011-01-18 17:04:03 | 1 |
Anyone have an idea of what I should be looking at in a situation like this? Does the 'goto' field look fine?
