Re: [spamdyke-users] Error on Qmail Toaster Install
[This is a reply to https://www.mail-archive.com/spamdyke-users@spamdyke.org/msg03900.html—I don't have the original messages to this post probably won't thread correctly.] When running `spamdyke --config-test` I experienced a `free(): invalid pointer` error similar to Jeff's, but found the problem: my morercpthosts file started with a blank line, then a line starting with a #, a bit like this: --- #example.com host1.com host2.com host3.com … --- Here's the error output: http://pastebin.com/d2tt8ah2 The solution was to delete these two useless lines from morercpthosts and it worked. spamdyke could catch this error if it parsed the file in a smarter way (accepting only lines with valid domains or displaying an error if unacceptable characters were found.

[spamdyke-users] Avoiding greylisting delays by making many exceptions
I'm new to greylisting, and have just set up spamdyke on a mail server with a few hundred users. Immediately my colleagues and I got annoyed with delayed deliveries to our personal addresses ;P. I'm wondering if it would be a reasonable solution to create a `graylist-exception-rdns-file` containing the top 500 or so most common reputable rdns hosts? Surely no spam would be expected to originate from rdns origins matching, e.g.: .twitter.com .apple.com .amazonses.com .gmail.com …etc Using a list such as http://moz.com/top500 might be a good start. I hope this method would allow the prevention of delivery delays from the hosts people rely on most, while still inhibiting spam from the other 99.9% of rdns hosts. Does anybody have experience using this method? I'm trying it now, and will report back if I have any issues. But I don't have a history of using greylisting, so not sure if it is a best practice.

Re: [spamdyke-users] Avoiding greylisting delays by making many exceptions
At the suggestion of others here, I turned OFF greylisting last year, after having used it for years before that. My spam level didn't increase one bit. I think the RBL sites are pretty good at identifying spam originations, so I use thatmethod now.

I'd like to know how y'all value greylisting in today's internet climate. I installed spamdyke at the same time as enabling several other spamassasin network rules. The result is, our users are seeing far less spam. But with all the changes, it's hard to say what is providing the most benefit (and what isn't). We were using rblsmtpd before, so the blocklists aren't a new aspect. Perhaps I'lll leave greylisting enabled for another week, then turn it off and go another week and compare the metrics.

Re: [spamdyke-users] Avoiding greylisting delays by making many exceptions
I also remember this discussion but it was quite a while ago. I had subsequently removed greylisting as well with no noticeable increase in spam. I did add Sam's hunter_seeker script and it did make a difference. However, I haven't seen any new websites added to that blocklist so I wonder whether that is as effective as it used to be.

[spamdyke-users] broken hunter_seeker URL
Sam, The URLs for hunter_seeker and spamtrap you offered us in 2013 are broken: http://www.spamdyke.org/releases/hunter_seeker/ http://www.spamdyke.org/releases/spamtrap/ Has this project moved? And is this script still as effective as it was? I'd like to know its current status before implementing it.
