Thanks. I was going to look into alternate transports. For the test, discard may be what we're looking for. For the invalid domains, 'error' is much more appropriate. On Wed, Apr 4, 2012 at 1:08 PM, Noel Jones wrote: > On 4/4/2012 2:48 PM, Edward Morbius wrote: >>

Disable delivery for a specific domain (or list of domains)?

2012-04-04 Thread Edward Morbius
I'd like to set up a delivery rule / method which simply rejects delivery for a specific domain (or set of domains). The immediate need is testing based on a domain we control. We've also got an issue of stale contacts for expired domains which pile up in our queues but I haven't addressed them.

Several of our peer mail systems (outbound) seem to take a while responding to initial SMTP connections. Is there any particularly dread pitfall to watch out for in bumping these values up? 20s for connection, 40s for HELO is where we're at presently. My main fear would be resource exhaustion, t

Delivery rule / transport to fail mail to certain domains?

2011-10-06 Thread Edward Morbius
List management at KPSU isn't what it could be. We've got contacts for a few domains which haven't existed in human memory, and whose messages gum up our works. While I work with client relations to mop up the mess, would it be possible to define a delivery rule and assign domains to it such that
