[rt-users] Emails not getting through spam filters of many ISP's due to "Unknown Error"

[Joanne Keown]

Hi RT gurus,

I have a situation where emails from RT are going into SOME  ISP email inboxes but not others.  Gmail & Hotmail are OK, however, Optusnet and others are being filtered out as spam with the following message:

Unknown address error ('453', ['#4.1.8 Domain of sender address <root at rt.coloradogroup.com.au<mailto:root at rt.coloradogroup.com.au>> does not exist']) []

Is there somewhere where the config allows me to change the sender address to something like rt at coloradogroup.com.au<mailto:rt at coloradogroup.com.au>?

I have set the following email address into my Queue config for "Reply Address" and "Comment Address", but as far as I can tell it doesn't seem to control that:

*         customerservice at dianaferrari.com.au

Once again, any assistance would be greatly appreciated.

Many thanks and regards
Jo
