Hi folks
OS- Debian Etch
Xen
postfix
courier
perdition
perdition-mysql
MySQL
Single public IP
Dom0 - Debian Etch workstation
Server-1, domU1 for routing with perdition and perdition-mysql
installed
Server-2, domU2, mail server for domain-A
Server-3, domU3, mail server for domain-B
etc.
This is server virtualization for testing. The whole system is working
nicely. Mails of domain-A are delivered to Server-2, mails of domain-B
delivered to Server-3, etc. Roaming clients can login their servers to
download mails. But they can't send mails via their server.
Please advise how to configure perdition allowing roaming clients to
send mails via their server. OR I have to use another solution? TIA
B.R.

I am guessing that this is some kind of configuration issue with
the SMTP daemons in Server-2 and Server-3. When you say that roaming
users can't send mailis via their server, what exactly isn't happening?

So you have the MXs for your domains pointing to postfix instance on that
single IP machine that acts as a gateway and also runs perdition,
forwarding mails to the respective sub-servers?
Perdition only deals with POP/IMAP, you need to use something else for
SMTP.
Is there a specific reason the mail _needs_ to be sent through their
respective domain servers? Can't you just have the gateway node handle it
all? (of course in real life you really want this to be at least a 2 node
HA cluster)
If you need it to go through their servers, you could force-forward the
mails submitted (MSA) to the gateway machine to the correct domain server
by some postfix magic based on the login credentials.
I'm pretty sure I could do something like this with Exim, for postfix you
need to find a postfix guru I guess.

Hi Christian,
Thanks for your advice.
So you have the MXs for your domains pointing to
postfix instance on
that
single IP machine that acts as a gateway and also runs perdition,
forwarding mails to the respective sub-servers?
YES
Perdition only deals with POP/IMAP, you need to use
something else
for
SMTP.
I suppose SMTP AUTH can do the job. But this is NOT Perdition way.
I have another routing mail server on this Xen box without Perdition
installed. It also works without problem routing incoming mails to
their own mail server. But roaming mail clients can neither login to
send nor login to download mails on their mail servers.
Is there a specific reason the mail _needs_ to be sent
through their
respective domain servers? Can't you just have the gateway node
handle it
all? (of course in real life you really want this to be at least a 2
node
HA cluster)
I thinks I can make use of the routing mail server to allow roaming
mail clients sending mails. For good housekeeping I prefer to go the
former way so that outbound mails can be retained on their own mail
servers rather than having all records on the routing mail server.
This is an experiment. In real life it is not feasible to have 100
domains pointing at one public IP for sending and downloading mails.
On Xen box it is possible running >100 servers as domU concurrently.
Although I haven't tested it. However I did try running 25 servers
concurrently as domU on this Xen box without problem.
If you need it to go through their servers, you could
force-forward
the
mails submitted (MSA) to the gateway machine to the correct domain
server
by some postfix magic based on the login credentials.
I'm pretty sure I could do something like this with Exim, for postfix
you
need to find a postfix guru I guess.
Could you please explain in more detail. Pointer would be appreciated.
TIA
