Incoming SMTP / MX servers

# How to configure incoming MX/SMTP servers

In some situations you will want 1 or more incoming smtp servers, there are some settings you can use to optimize performance in this situation:

Backend server ip address 1.1.1.1

Incoming MX server address 2.2.2.2

On the backend system (1.1.1.1) set:

> g_spam_allow "2.2.2.2" (Version 3.0 and earlier)
> g_gateway_allow "2.2.2.2" (Version 3.1 and later)
> g_spf_skip "2.2.2.2" (Version 3.0 and earlier)
> g_received_name "your.domain"

On the incoming MX server set:

> g_received_name "your.domain"
> g_vanish_bad_bounces "true"
> g_send_max "40"
> g_send_nolimit "true" (version 3.1 and later)
> g_send_max_perdom "20" (Version 3.0 and earlier)
