Personally I think spam block lists are crap because they function so poorly and arbitrarily, but it is an ongoing problem for us when our shared email servers spend a lot of time on somebody's block list.
I see that the Dreamhost mail server for our new account is currently on Spamcop's block list, and seems to spend about 20% of the time there (see below). Does Dreamhost have any policy on addressing this problem?
Query bl.spamcop.net - 220.127.116.11 (postalmail-mx2.dreamhost.com)
18.104.22.168 listed in bl.spamcop.net (127.0.0.2)
If there are no reports of ongoing objectionable email from this system it will be delisted automatically in approximately 21 hours.
Causes of listing
- System has sent mail to SpamCop spam traps in the past week (spam traps are secret, no reports or evidence are provided by SpamCop)
- It appears this listing is caused by misdirected bounces. We have a FAQ which covers this topic: Why auto-responses are bad (Misdirected bounces). Please read this FAQ and heed the advice contained in it.
Additional potential problems
(these factors do not directly result in spamcop listing)
- System administrator has already delisted this system once
Because of the above problems, express-delisting is not available
In the past 124.5 days, it has been listed 21 times for a total of 23.8 days
