This morning, I'm putting mimedefang into production, just for virus
and attachment checks. I'm seeing a lot of "Please try again later"
responses from mimedefang. The problem is, this same sever is used
by my local users (not just remote MTAs), and we don't want them
getting that type of response.
What do I need to adjust to make this happen less? (sendmail's load
threshold is much higher than the load I'm seeing on teh system, so I
don't think it's that)
Specifically, I wouldn't mind having it do this more for remote
senders and less for local senders. I just don't want local senders
to see this much (if at all).
If the answer is "adjust MX_MAXIMUM in the rc script", then I found it.
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
higher).
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)
