MailScanner slowwing down

[Mail Admin]

Martin, sorry for bothering you, but is there a description on how smf-sav
actually works. How does it check the recipient of my domains? Does it know
somehow  how to get to the exchange server for each domain>? I cant find any
descriptions on the workings?

 

Thanks a lot

Hi

 

you need to do a lookup on each address rather than keeping it a file you
have to maintain - smf-sav can do this quite easily although it's main
purpose it to check senders it can also check recipients

The unknown recipients would solve a lot of the problems.

I'm not sure if I can get my head around this though.

The Server has some local domains with pop3 and the big domains I relay on
to their Exchange Server.

I'd love to put all the valid exchange users in a file and allow the system
to only accept for thes valid addresses, but is there an easy way?  So my
exchange domains I lookup a file of addresses and other local I use the
access file?

Thanks

See

and

Dropping unknown recipients and having a local caching nameserver are
generally the first things to sort, then look at the number of children and
batch size...

Hi All,

 

Recently I am finding that the amount of incoming mail through my
MailScanner Server  is really slowing down things.  There is a heavy load
now since I took on a domain that seems to me well spammed. Yesterdays
processing processed 22,000 emails @88% Spam approx.

Server Spec POWEREDGE 1850 XEON 2.8GHZ/2MB 800FSB - WITH 2 GIG RAM and RAID
1  Configuration on two Disks RPM 10K. Its Running Fedora Core 5, Send Mail
8.13.8-1.fc5 with MailScanner 4.69.7-1 with SA, Razor, DCC., MailWatch V1

Its working very well blocking spam, but only in the last couple of days its
got really slow. 

Any ideas on how to reduce the load on this server>? By blocking mail at the
MTA before it hits MS? OR Tweaking my processes?

What do the Experts think on the Server Spec, for the amount of traffic?

I'd appreciate any help

 

Regards

Kevin
