Scalix with an external SMTP proxy

[boombastic]

Hi,

We have scenario where we have an external SMTP proxy server as part of our firewall /Astaro ( http://www.astaro.com ) which acts as a content filter (providing anti spam, antivirus capabilities.).

We can receive email from outside world and it gets delivered correctly to scalix... We are however not able to send any outbound email.

We would be much obliged if someone can point us in the right direction so that we can make scalix aware of the smtp proxy server and use the proxy server to send out all mail destined for internet email addresses...

The below image gives a rough idea of the configuration

Scalix version is 10.0.1.3 on CentOS 4.4

Well, firstly, in /etc/mail/sendmail.mc, change the option

Code: Select all

dnl define(`SMART_HOST',`smtp.isp.com')

to

Code: Select all

define(`SMART_HOST',`smtp-proxy.xyz.mail.com')

where smtp-proxy.xyz.mail.com is the DNS name of the Astaro machine.

Then, in /etc/mail, do

Code: Select all

m4 sendmail.mc > sendmail.cf
omsendin

Hope that works for you.
