> don't you run other checks that refuse those spammers? But yes, I do, however, as Jan Ingvoldstad pointed out, spammers get smarter. I use SPF checks, but they now use dedicated hosting services where there's no SPF record, or they use domains with relaxed SPF. This makes SPF checks useless, obviously.
There's pythonfilter and spamassassin+amavis, but that's my REAL problem here. Imagine that around 12 PM my server may receive bombardment of around 300 messages PER MINUTE - and I'm not talking of those "multiple receipients" messages. It probably wouldn't be a problem with a quite recent machine, but this one (as with most educational institutions) it not - it's a seven-years-old system with single Xeon 5110, so you can imagine the load when the spike happens. > usually, it does not only matter hof much of spam gets rejected, but also > how much of ham is rejected. For me it was just 6 sources, that were "false positives": the only notable ones were facebook (but hey, that's a company account :) ), hotmail (added their network appropiately) and polish tlen.pl. So, in conclusion: for me strict HELO checking is simply a way not to kill the server prematurely. ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
