they are local domains though.

i am talking about sending out for my large number of domains that are on a few different email servers.

if i use xeams in normal mode it will try and deliver locally for any domains in the list.

so if a user on server1 sends a message to a domain on server2 xeams will try and deliver it locally.

if i use xeams in firewall mode i have to specify where each domain will be delivered to (works but becomes very hard to manage when we are talking about a large number of domains that i might not control dns for, so when my client updates there mx record i would like xeams to follow, vs having to manually make the change.)

and the only reason i would like to add my domains to the local domains file is so i can be notified when we are sending out email for not one of our domains(aka spam)

i dont use the file to check if i can relay i have just trusted the ip's of my mail servers.

sorry if this is confusing.
