I've recently switched to Postfix as my MTA, and dbmail using lmtp to
locally carry emails between Postfix and my Postgresql email store.
It's a great system. Dbmail can be installed from FC6 using the
[Add/Remove] menu options which install the demail daemons in the
/usr/sbin directory, creates the services to automatically start
everything when the system is booted, and automatically creates the
dbmail user and dbmail group under which dbmail runs. All I had to do,
once I had the Add/Remove dialog window displayed on my FC6 server, was
search on dbmail and then check on the dbmail binaries that appeared,
and then click on {Apply]. Dbmail also supports MySQL and SQLite as
email stores in addition to PostgreSQL database server. The tarball
would have to be downloaded to obtain the sql file from which the
database is built, then it's just a matter of creating the dbmail
database, the dbmail user and password, and the dbmail group, and
reading in the sql file which creates all the tables, indexes ,etc in
the PostgreSQL database server.
Dbmail also has a web based GUI administrative tool named DBMA v2.4.9 in
my case, which makes it easy to add new users, set user permissions, do
searches of email, and keep the PostgreSQL database clean and tidy.
Each user password is stored in a PostgreSQL dbmail table using plain,
md5sum, md4, or crypt formats depending on admin preferences. Users
authenticate to a PostgreSQL table, so there is no need to create a
Linux user account to add new email users.
Security, speed, and scalability in dbmail is as good as your PostgreSQL
database configuration and clusters are supported.
I can backup my email system every night with a hot backup from a
crontab job created with webmin, so the email server need not be
interrupted.
Dbmail is much easier to install and configure than was the Cyrus imap
system I previously used.
Dbmail can be configured to use various email filters and virus scanners
to filter out unwanted or dangerous emails, but I havn't gotten into any
of that yet.
Dbmail also supports server sided sieve filtering or redirecting of
email into designated folders and auto/vacation reply. All the sieve
scripts can be created using the squirrelmail GUI plugin and works
exactly like it did under Cyrus_imapd.
