Postfix - sender_dependent_relayhost_maps

[KevinFrance]

I am trying to use this to route e-mails by two different routes dependent on the orginators domain.

Unfortunaltey, it does not aooear to read the table.

Below are copies of the main.cg and bysenderrelay files.

Can anyone advise how I might resolve this?

Are there any errors in your mail log?

[KevinFrance]

No, all that appears in the log is that relay is none.

[falko]

Did you run
postmap /etc/postfix/bysenderrelay?
Can you remove the relay_domains = line?

[KevinFrance]

Yes I did run postmap /etc/postfix/bysenderrelay

I will remove relay_domains = line and let you know the result.
