Two Servers and Two Sets of Email Addresses
We are hosting a clients web site but not email.
Yet we need one email to reside on our server as a catch all since their host does not allow this. It is key for our mass email software (

On their serves I will setup
MX 30 theirserver
MX 50 our ispconfig server

On our server under MX I was going to enter
Domain Settings
--Hostname blank
--Prio 50
--MailServer Theirs

--Hostname blank
--Prio 90
--MailServer Ours

This way if I send them an email from our server they still get it on their server.
And then if the catchall email on their server gets and email it will forward it to our server which should allow it in.

Also I am not sure how the External and Local Email servers in ISPCONFIG effect all this.
Right now even with the above setup it seems I need to set all of these to External Email Server?

Any advices would be appreciated

External mailserver instructs postfix to not handle emails for this domain as a local account. The external mailserver setting does not affect DNS.

Thanks Till so that means if I leave all of them set to Local
and set the MX as above it should all work out?

The problem is that if you set it to local and try to send an email to them, it will not go to the other server, but stay on yours because Postfix thinks that it must handle that email.

If you set it to external, then Postfix will never accept emails for that domain which means that the catchAll won't work. :(
