And there is the problem!
I have configured ONE inbound "courier-mta-ssl" and curently FIVE
"courier-imap-ssl" since I have too much $USER accessing the IMAP
at the same time. Arround 600-1400 $USER of over 17.000 Accounts
but increasing.
The mailboxes itself are on 5 seperated NFS-Servers.
I have setup a round robin for <mail.mydomain.tld> for the IMAP
Servers but it does not realy work, specialy if $USER use the
Webinterface on <webmail.mydomain.tld> which use 2 Servers currently.
Any hints how to setup correctly round robin for:
1) <webmail.mydomain.tld>
The 2 Webmail (I use my own PHP5-Apache interface and
not sqwebmail, since it does not work HOW I like)
2) <mail.mydomain.tld>
The 5 IMAP servers
3) <smtp.mydomain.tld>
The InBound "courier-mta-ssl" which do currently SPAM-
Filtering too since I do not know HOW to setup this on
external Servers... I like to set up this server for
SMTP-Level filtering only and then use external Servers
for Virus and other SPAM filtering.
Thanks, Greetings and nice Day
