Hi all,
I am still having local delivery delay issues. Here is brief
description of my system:
MySQL 3.23.56
courier-mta 0.42.2 with mysql auth
courier imap with mysql auth
courier pop3d with mysql auth
RAV antivirus 8.4
Spamassassin 2.55
Razor 2.36
approximately 1100 customers
Intel(R) Pentium(R) 4 CPU 1.60GHz
cpu MHz : 1615.935
hda: 156301488 sectors (80026 MB) w/2048KiB Cache, CHS=9729/255/63,
UDMA(100)
[EMAIL PROTECTED] cdick]# cat /proc/meminfo
total: used: free: shared: buffers: cached:
Mem: 924430336 915738624 8691712 0 121597952 469168128
Swap: 534601728 91127808 443473920
MemTotal: 902764 kB
RAV does not appear to be the issue as mail is getting through the
input process. When local deliveries are attempted, I am calling maildrop
from the .courier file. Maildrop uses the following .mailfilter recipe:
xfilter "/usr/bin/spamc"
if (/^X-Spam-Flag: YES/)
{
to "./Maildir/.xspam/"
}
I have worked with Sam for a couple of hours and implemented some
of his suggestions. The problem still seems to exist and seems to be
memory related (ie: when I get into using SWAP, local deliveries slow
down).
My question is, should my configuration be able to support 1100
customers effectively? Or are the 24 hour delays expected due to
spamassassin having to process each message.
I suspect a potential memory leak somewhere which would explain
why I am running into SWAP. Does anyone have a similar setup? Have you
also found delays with your mail?
I have two suggestions left to implement. One is to move mysql to
a remote machine. The second is to try my hand a load balancing a couple
of servers.
I have already built another machine and am in the process of
porting many users to it. However, I am afraid that as I load this new
server up, I will run into the same issues. Once I have a load balancing
solution in place, adding new machines to the config shouldn't be
difficult, however, if there is something fundamental I am missing, it
will save me from having to buy a new server for the cluster every few
months.
Thoughts, suggestions? Thanks in advance for any info you can
supply that might be of relevance to me. Have a good day.
