Hello
I have a question about a problem that we run into regarding Postfix and
MySQL connection.
We have 3 servers running Percona XtraDB Cluster for mysql master-master
cluster, and 2 frontend servers running HAProxy + KeepAlived to balance
the traffic. We try to balance MySQL requests in HAPr
machine B or machine C to machine A.
can it be done?
If machine C is down, relay machine B will spool all emails till
machine C is up.
what configuration adjustment should I make for relay machine B?
is there a way to adjust the mail holding days in the relay machine B?
any help is appreciated.

Hello,
I want to find out if there is a mail in the queue for two days using

that the time stamp for the mails in the queue changes and alway

I think that postfwd can do all of this already, working as a policy

No need to complicate postfix any further: it is an MTA, and should
concentrate on mail delivery. There is a reason that you can hook up a
myriad of external tools into postfix.

because something is wrong, there will be no postfix logging.
So: to check why postfixadmin cannot send the e-mail, check the error
logging of php/apache until you find an error line telling you why the

until the message hits your postfix install.

Anyway, the administrator can always simply remove support for the

You'd still be better off feeding messages to SA from the MTA, and let
sieve just move messages around based on added headers.

pfa has this covered by adding a record in the alias table for both
aliases (b...@example.com->a...@example.com) and mailboxes
(a...@example.com->a...@example.com). This means that a list of all mail
addresses (aliases and mailboxes) are available in alias.address, and
that a single query on that table is enough to check all variants.
If you don't like that design (I don't, but I have other things to worry
about), write a difficult query or again, split the work over separate
lookups: one for aliases in alias domains, and one for accounts in alias
domains.
