If you don't care if some messages are not checked, there is maybe a way to implement this:

There are some options in the INPUT_MAIL_FILTER statement in the sendmail configuration. There you can specify what should be done if the milter-socket is not reachable. The problem is, that the socket is reachable all the time, even mimedefang has no free slaves. So this will not help.

So how to modify mimedefang this way, that it don't send "please try again later" if it's busy. How to implement ? I don't know, but maybe someone in the list ;)

Hm.  Well, maybe not.  After adjusting that to 20 and 15, that's not 
really helping.  I assumed that maybe that number was causing me a 
problem because I was running out of slaves to process my incoming 
messages.  Increasing it just increased my system load, but didn't make 
the problem go away (and at 20, the load was starting to close in on 
what our sendmail load thresholds are at ... so I wasn't going to go 

Setting it lower seems like it would make the problem worse, maybe.

I'm thinking it might be that we run our front line mail servers on 
tiny/hold hardware (sunblade 150's and sunfire v100's, 2 of each, and 
so far I had only installed this on one of the sunblades).  Sophos 
Puremessage recommended that we not go with anything weaker than a 
Sunfire v210 ... so maybe it's the same issue here: if we're going to 
milter, we're going to have to upgrade.

(we plan to upgrade hardware soon, but this was supposed to be a 
middle-term upgrade of software only)

So, I guess no mimedefang in production at work yet.

(which is sad, because I REALLY love using it at home, and it was set 
up just fine on our test machines ... guess I have to wait til we get 
the new hardware)
