Dear Everyone,
Has anyone tried setting up a separate SMTP server to manage outgoing
traffic.
Let me draw this in your mind. I currently have 6 mail servers with 300
domains hosted on each server averaging 20 email accounts per domain and
using qmail but experiencing high queue due to outgoing smtp connection
(no spams) all emails are legitimate. Majority of our clients are
freight forwarders, remittance, multimedia company, etc. Basically,
everyone maximizes the use of their email including attachments,
marketing ads, and several mail activity. What I am thinking is to setup
a separate SMTP where all my 6 mail servers connect to send only
messages and not receive.
Is my setup possible? Anyone kind enough to provide documentation of my
stated dilemma? I would appreciate any kind response from you qmail
experts.
Thanks in advance.

That's quite a good idea actually. My intention for the future of QMT is
to make separate role-oriented servers such as this (a submission
server), which will be easily combined with others to make up what we
presently know as QMT.
In order to do this, simply build a new (virtual) qmt host. You can omit
the packages you won't be needing such as squirrelmail, courier,
maildrop, etc.
Once you have the server built, modify the
/home/vpopmail/etc/vpopmail.mysql file to point to the host with your
mysql database, and ... oops. You have 6 of these, don't you? So it's
not going to be quite so easy.
I'm thinking that you might want to set up a vpopmail/mysql database on
the submission server which contains account information for all of the
domains. You might be able to use mysql's replication feature to make
this database a secondary to all 6 of your existing vpopmail databases,
but I don't know if that's possible, or if you might run into any
clashing of keys between the databases. There shouldn't be, but I
haven't looked at that schema in a while.
I'm going to ask for other opinions at this point. Bharath, you here?
Anyone else have an idea about this? Please chime in. :)
Interesting project, Fernando. I hope we can help you out with it.
