Probably won't happen, but you might consider switching to a different FS format, which doesn't have the same issues... Also, consider whether qmail-scanner is suffering from this, or is this performance issue only noticed when you do an ls on that folder ??
well, to be honest, i'm not certain there's a performance issue from it. it's just that in my experience pretty much all unix/unixlike filesystems suffer once total file count becomes enormous. maybe i'm just being superstitious.
Also, personally, rather than quarantining, I find it much more preferable to return a 5xx code and reject the email. This way, even if it is a false positive, the sender is informed of the issue. This probably has other negative impacts, but IMO, it was the best decision. I don't need to worry about the quarantine growing too big, I don't need to worry about 'losing' email, etc... I can safely say that *every* email is either delivered, or bounced. I imagine that for you, it would greatly reduce any tech support requirements (hey, I only get an average of 1200/day, which I just now checked, I didn't really think it was that high, oh, and that is only counting the primary MX)
it'd be great if i could do the rejection, but i run qmail-scanner on a proxy antispam/antivirus server - my four MX servers feed into the AS/AV server via smtproutes, and from there to the popserver. so if i rejected, i'd just be telling my own MXes that i don't like the message.
in the interim, per Salvatore's recommendations, I'm modifying my other spam parameters a bit. for now i'm just gradually lowering my delete threshold. i don't want to get too severe with that, obviously, but i've been very cautious so far - spamassassin tagging begins at 4.0, quarantining at 10.0, and delete at 25.0. i've lowered it to 22.0 for now. seeing as i don't think i've had but maybe two false positive quarantines at 10.0 in the last year, i can probably lower it considerably, but caution is alway the order of the day when making drastic decisions/changes....
