[SLUG] postgrey
Does anybody have an opinion about postgrey? Does it annoy legitimate users? Slow down the system? Create false positives? Work as intended? Any other thoughts? thanks David. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Work as intended? Any other thoughts? We use it on Rusty (SLUG's mail/web server), and it's the main cause of mailing list outages. That said, we have an extremely manky configuration hacked together over 10 years, so I'm sure a clean room implementation wouldn't have the same issues. From my experience it does a good job of filtering spam.

Re: [SLUG] postgrey
I use it on my mail server and I love it. The only time a user notices it is when they're on the phone and someone says they've just sent something. Even then it's only the first time as any further emails in the next 30 days are white listed from that address, IP, combo so no further delays as long as they get an email from them at least once a month. I have changed the delay time from the default 10 minutes to 60 seconds as I've found that to be enough to stop the spam but YMMV.

It has proved to reduce UCE/UBE alot for me over the years but a downside that may or may not bother you/your users is the delay it brings to emails from new people. My personal emails this is not a problem but in the workplace it may not be an option. eg: If your on the phone with someone new you can't have an email sent to you during the phone call and continue your call around the email as the grey listing will get it and be delayed. thanks David. -- Regards Mick Pollard ( lunix ) BOFH Excuse of the day: Redundant Hardware Destabilisation Warning -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

I use policyd for greylisting, it occasionally annoys me... when I need something from some remote site... as for the users, I told them 'that how it is, don't expect instant email, expect improvements in UCE rejection' all in all, I find greylisting useful -- Voytek -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

I use that and some dnsRBL's and get ~1 spam a week. one client was getting ~3000 spam emails a day (to one mailbox) took that down to ~2 in one hit. Its been running at their site for ~2 years now and despite their initial trepidation about emails not being instant I don't think they even know it exists now, they just don't get spam. I've had more problems with the dnsRBL's going wonky. What I would really like to get is a DNS whitelist for Australian providers. You can do some cool things btw, I replicated the postgrey mysql backend between my mail servers (along with the mysqldb holding the mail) and it all worked fine, the occasional server would send to the primary then bounce to the secondary and get knocked back again but it didn't seem to bother anything. I mainly did it to move the database while I was migrating the hosts, but it seemed cool enough to just leave in place ;- -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
