Sendmail Woes

[benjithegreat98]

I am using sendmail as a means to block spam. We have an old 400 MHz PC with 384 Mb of RAM. We use this computer to accept the mail into our organization and relay it to our Domino server. We do this because the Domino server is too old to use DNS Blacklists and we don't have the money to upgrade it for that.

The problem is that when I boot up slack, free -omt will report 85 M used and 291M free. The next day or 16 hrs later it will read 275M used 101M free. and it will continue to shrink. When I do "ps aux" or "top" it doesn't report anything using that much memory. I also had this problem with Redhat 9 and sendmail 8.12.8. I thought it was spamassassin doing it but I was wrong because I turned it off and it still persisted. So I moved to Slack and it is still doing it.

Unix uses memory efficiently and will use up any remaining memory for buffers and cache.
Don't worry about but enjoy how well it performs.

When I was running RH9 w/ spamassain and sendmail I would run out of memory. I could hear the hard drive churning because the swap space was being used heavily. This would happen every 4 hours or so. Spamd was automatically killed to end it. While this was happening I could not do anything. Everything was unresponsive, or at least _very_ latent. It would take minutes for keystroke to appear in the command line. And forget about them being executed. Connections were being denied as well (ie. no incoming mail). I eventually had to stop using spamassassin. But I'll let it run without interviening for a couple of days to see how it goes this time. Hmmm. Maybe I should have said all that earlier.
