problems with BLU mail?

[gaf at blu.org (Jerry Feldman)]

It appears to be a combination of things. 
1. The mailman qrunner tends to get hung up every once in a while. My 
solution to this in October was to set up an hourly mailman cron to 
restart the qrunners. However I turned that off on Wednesday, but the 
problem came back. Last night I had 386 messages on the mailman queue, 
this morning it is down to 85. 

2. The combination of incoming SPAM traffic, SPAMassasin, and mailscanner 
seem to have postfix taking too long to read mail. 

3. There are a number of bad addresses on our listserv resulting from the 
restoration of some lists. This also slows down the system, but these are 
quickly getting purged as postfix decides to bounce them or I manually 
remove them. 

4. I'm also seeing some issues with the hourly cron job that JABR set up 
for the virus updates. 

The best solution would be to stop SPAM on the Internet :-)
More of a stopgap solution for us would be to acquire a new system. I'd 
love to have something like an HP ProLiant DL380G4 or G5. Jokingly I 
mentioned that to one of the lists and they are now passing the hat. A 
more realistic approach is to utilize an existing low-end server that JABR 
bought via eBay as a dedicated mail server. I'm also checking with some 
contacts to see if I can obtain a donated system. Ideally, if we get a 
decent system, we would like to run virtualization.
