Postfix stops accepting connections when primary dns is down.

I'm kind of baffled. It's probably some really stupid issue that I'm going to hang my head in shame over, but I really can't wrap my head around it. I've got a postfix box. It's accepting external mail fine. [And has been for some time.] It's pointed at a couple of caching name-servers in the lo

So, I've done some searches and reviewed the mailing list and don't find much... [Though effectively searching this "topic" is difficult, so it's certainly possible I've missed something...] For example, lfd/cfs allow you to track that user "X" sent Y piece of mail, and it will alert you. Now I

I've done a few searches and don't really turn up anything - so my apologies if this is an "old" already answered question. [If you could point me in the right direction for the discussion somewhere that would be nice...] So, here's what I want, and I'm not sure how best to go about it. Platfor

Ok, I started down this path a while back and left it on the shelf - but now I'm back on the case, but I'm still baffled and don't know where else to ask. If you'd point me in the right direction, I'd be very grateful. I'll also include the problem here so you can take a crack at it too. --- In
