Blacklist providers – to trust…
I am often asked whcih blocklist providers do I use / trust not to get mail filtered becouse of bad blacklist provider.
On my servers I am using three lists (sorted by quality – my personal opinion 🙂 ):
zen.spamhaus.org – a combination of three spamhaus.org lists (SBL, XBL and PBL)
bl.spamcop.net – Spamcop blacklist
list.dsbl.org – Distributed sender blackhole list
I use this three lists without getting in troubles – at least for now. I suggest that you regularly check your SMTP logs to see how list are working.
I always notify sender that it was blocked by a blacklist.
Here is an example from and Exchange 2007 SMTP recieve log:
> “220 mail.mydomain.com Microsoft ESMTP MAIL Service ready”
< EHLO [87.69.94.190],
> 250-mail.mydomain.com Hello [87.69.94.190],
< MAIL FROM:<cathiFerm@flagpeakproperties.com> SIZE=656,
> 250 2.1.0 Sender OK,
< RCPT TO:<xxx.xxx@mydomain.com>,
> 550 5.7.1 Your IP is blacklisted. http://www.spamhaus.org,
< QUIT
> 221 2.0.0 Service closing transmission channel
