How to allow roaming client to send mails via its mail server

UNIX for Advanced & Expert Users
1

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

Hi sumitpandya,

Thanks for your advice.

I have 2 routing mail servers on the Xen box.

Routing Mail Server-1A - without Perdition packages installed. Roaming mail clients can't login to send/receive mails.

Routing Mail Server-1B - with Perdition packages installed. Roaming mail clients can login to receive mails but unable to send mails.

Both of them have similar packages installed, running without problem. Incoming mails can be routed to their own servers. Only ONE public IP is used.

Whether following documents are relevant for my application;

Could you please explain in more detail. Google search on "SSL related extensions into respective document" can't find relevant document. TIA
