We have used enigmail to encrypt messages for long time and very happy with it, however lately we get problem with some anti-spamfilters like zen.spamhaus.org and cbl.abuseat.org
As the keyword www.enigmail.net appear in the encrypted message header we get the mail return saying the following:
SMTP error from remote server after transfer of mail text:
521 A URL (www.enigmail.net) in the email resolved to a blacklisted IP:
521 The IP 188.8.131.52 is Blacklisted by zen.spamhaus.org.
http://www.spamhaus.org/query/bl?ip=184.108.40.206 -- 521 The IP
220.127.116.11 is Blacklisted by cbl.abuseat.org. Blocked - see
http://cbl.abuseat.org/lookup.cgi?ip=18.104.22.168 -- .
Is this something you have to get whitelisted with zen.spamhaus.org and cbl.abuseat.org or do I missunderstand how this works?
Hope on a quick answer :)
Kind Regards Morten
There is nothing I (or we) can do about it. Enigmail.net is running on a shared server operated by a professional hosting company.
I'd suggest you disable the option "Add Enigmail comment in OpenPGP signature" in the "Advanced" section of the OpenPGP preferences.
Hi. Thanks for your answer.
It seems like they finaly has been whitelisted
Thanks for the tip on howto if it happens again
