I'm curious if anyone uses DBMail with postfix to store mail.
If so, what is the performance, could it be ran on
the same system as posfix while receiving thousands of emails a day?
"some thousands of mails" are peanuts
make sure you have neough RAM and a good innodb-configuration
[cut]
innodb-settings froma production server with some hundret users
and currently 50.000 messages with totally 9 GB mailsize
for these settings you need a machine with around 8 GB RAM
and MySQL>= 5.5.8
Just curious. Why use dbmail as storage for mails?
I run several mail servers with exim + dovecot and Maildir storage. Just
for example one of my server has 2600 mailboxes for a total of 110 Gb of
data, dunno how many mails. It's a Xeon quad core with 2 Gb ram and 2
sata disk in raid1, load average is never > 2.
pop3 and imap access, relay with smtp authenticated for users.
You don't have to backup a big database, just many small files, so you
can restore easy and capillar, how you restore one message or one
mailbox with dbmail? I don't think dbmail is faster or safer than a
Maildir setup ora a Dbox (Dovecot's own high-performance mailbox format)
setup.
