Hi,
Recently we have migrated our e-mail servers to DBmail, so I thought I
could write a bit of encouraging words for the authors of DBmail.
We've set-up an redundant, highly-availiable and scalable system with
DBmail. The system is designed for multiple DBmail serves (currently
two), balanced via haproxy and two mysql servers in master/master
replication with single "active" server via ucarp.
Web frontend apps are RoundCube for users and DBMailAdmin for admins -
these are running on separate web servers (among other web pages on
these web servers). The availability of DBMailAdmin was crucial for us
as we needed a decent web admin tool for managing domains and users, so:
+1 for Zhang Huangbin, the author of DBMailAdmin!
DBmail servers are virtualized on VMware (each with just 2 GB RAM and 2
vCPU), MySQL servers are physical machines (just casual x86 servers, and
servers many other databases besides the DBmail database).
Currently we are hosting 110+ domains with about 500 email accounts in
total and cca. 15.000 processed (incoming+outgoing) emails per business day.
The system is working very well and besides the memory leaks (which are
handled by automatic DBmail processes restart when needed) we are very
satisfied with the performances and very low demands for resources. It
turns out that database is actually a good store for emails.
So, at this point I would like to thank the authors of DBmail for the
good work in the past and say: *just keep up the good work*!
Kind regards, Marko Kobal
CTO, Arctur d.o.o.
