Problems with Error 421

[Don O'Neil <li...@lizardhill.com>]

Ever since I upgraded to Exim 4.66 and my server load has gone up I've been
experiencing a lot of Error 421's (disconnection errors).

>From my google search it seems we may be memory/cpu/disk bound, and there
are suggestions on limiting the file size scanned, removing large rulesets,
etc..

I have searched the exim site looking for a way to limit the file size but I
can't find anything. Can someone suggest what I need to do to my
spamassassin transport config to limit the size of messages that are sent to
spam assassin to 100k (or less) and send the remaining though un-scanned.

Here's the exerpt from my exim.conf:

spamcheck:
  driver = pipe
  batch_max = 100
  command = /usr/sbin/exim -oMr spam-scanned -bS
  current_directory = "/tmp"
  group = mail
  home_directory = "/tmp"
  log_output
  message_prefix =
  message_suffix =
  return_fail_output
  no_return_path_add
  transport_filter = /usr/bin/spamc -u
${lookup{$domain}lsearch*{/etc/virtual/domainowners}{$value}}
  use_bsmtp
  user = mail

Thanks!

I don't know anything about Exim. However, I was able to dig this up from a
recent thread response to something from Steven Dickenson:

     ---
     Just add the following condition to your spam checking ACL.

     condition = ${if <{$message_size}{500k}{1}{0}}
     ---

So, I assume you would replace the 500k with 100k.
