[Kolab-devel] if i want kolab to do lmtp delivery to a different host

[Fabio Pietrosanti]

Does i have to modify this script?

/kolab/var/kolab/php/kolabfilter/kolabmailtransport.php

i see line like:
  function KolabMailTransport( $host = '127.0.0.1', $port = 2003 ) {
  function KolabLMTP( $host = '127.0.0.1', $port = 2003 ) {
  function KolabSMTP( $host = '127.0.0.1', $port = 25 ) {

What's about setting the $host variable in kolab.globals to allow the
decision of which LMTP server should be used to the sysadmin?
In this way we could have a separated cyrus lmtp server(even behind a
cyrus murder).
I think however that there are others configurations that need to be
modified to "split" the backend.

Correct me if i'm wrong.

There are some uml diagrams to show the flow of email inside kolab?

I'm now seeing that:

client->postfix(smtpd:25) -> content-filter(smtp-amavis:10024) ->
postfix(smtpd:10025->content-filter:/kolab/etc/resmgr/kolabfilter.php) ->
// Now the message is entered inside kolab filtering engine
kolabfilter.php that with the line of code "$smtp = new KolabSMTP(
'localhost', 10026 );" send back to postfix smtpd //
postfix(smtpd:10026)
// Now postfix can process the email sending it to transport specified
in main.cf "mailbox_transport = kolabmailboxfilter" //
-> /kolab/etc/resmgr/kolabmailboxfilter.php
// Now the second filter do it's own processing and at the end deliver
the email with the line of code "$lmtp = new KolabLMTP();" //
// KolabLMTP is defined in
/kolab/var/kolab/php/kolabfilter/kolabmailtransport.php as "function
KolabLMTP( $host = '127.0.0.1', $port = 2003 )" //
// On the port 2003 is running the Cyrus LMTPD as specified in
/kolab/etc/imapd/cyrus.conf "cmd="lmtpd -a" listen="127.0.0.1:2003"" //
-> cyrus(lmtpd:2003)-> bdb cyrus mailbox storage

Resuming the process of email delivery:
client->postfix(smtpd:25) -> content-filter(smtp-amavis:10024) ->
postfix(smtpd:10025->content-filter:/kolab/etc/resmgr/kolabfilter.php)
->
postfix(smtpd:10026->mailbox_transport:/kolab/etc/resmgr/kolabmailboxfilter.php)->
cyrus(lmtpd:2003)-> bdb cyrus mailbox storage

Is this process right?
