Hi folks,
I know you will probably think this is a small thing but my data bill
has grown
by 15GB per month over the last few months. Just watching the smtp log is
so frustrating as all but 1% of the connections result in actual mail
delivery.
Even then many of those connections result in spam.
Can anyone please suggest how I can slow this down some more? Does
anyone actually disable smtp connections during any given time periods?
By this I mean it seems most of my spam arrives after midnight and goes
away at about 6am.
Any ideas gratefully accepted.
I presume you're not using spamdyke. Spamdyke should easily block 80+%, 90+% in some cases. Heck, rbls alone should catch
30% or so.
If you're not using spamdyke, install it. The qtp-install-spamdyke script takes care of everything for you. Spamdyke is
slated to be included in the next stock QMT release (along with COS6 support).
If you are using spamdyke, please post your configuration file.
