[Maxima-discuss] Problems with mail deivery from Maxima mailing lists, was: test

[Roland S. <sal...@gm...>]

Thanks to Serge (!) who forwarded me a Delivery Rejection Response Mail which he had received when trying to send me CC
a mail from the list maxima-lang-fr, I found out a little more about the problem in the meantime. 

Remember: I can send mails from ma...@ro..., but I don't get any, neither from maxima-discuss nor from
maxima-lang-fr. For testing I also subscribed to maxima-discuss with a totally different forwarding mail address, which
is forwarded to my usual mail address. Here I don't get the mails either. On the other hand, I can send and receive
mails with this gmail account without problems.

The central error message in Serge's response was: 

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain roland-salz.de by
smtp.rzone.de. [some numbers ... (R.S.)]

The error that the other server returned was:
550 5.7.1 Recipients have complained about included content (B-URL) 

Today I got a first response from my provider:

"Die E-Mails werden bereits serverseitig zurückgewiesen, da die E-Mail eine URL/Domain beinhaltet, welche auf einer
Blacklist eingetragen ist. Zum Schutz der E-Mailserver und Ihrer Postfächer werden die E-Mails daher abgelehnt. Die
E-Mails können erst wieder zugestellt werden, wenn die URL/Domain von der Blacklist entfernt wurde. Hierzu muss sich
jedoch der Admin dieser Domain an den zuständigen Blacklistbetreiber wenden."

Some URL present in the mail (I'm not sure whether this means "sourceforge.net") is on a black list for email-servers.
In order to remove it from there, the admin of this URL has to contact the admin of whoever keeps this blacklist. Let's
hope this happens soon!

Best regards,
Roland

Normally blacklist providers ignore requests to un-blacklist sites as
they will be blacklisted again as soon as more spam is sent - and I
assume if you count all soureforge mailing lists together this will
happen in next to no time in most cases.

That means: There is a blacklist removal center at Spamhaus:
https://www.spamhaus.org/lookup/

216.34.181.88 and 217.72.192.67 (where I get the mailing list mails
from) aren't listed there - but as long as we don't know what this
"blacklist provider" is it is hard to find out if it keeps sourceforge
on its blacklist.

Kind regards,

   Gunter.

Maybe not sourceforge.net is on the blacklist, but the URL always present in the advertisement at the end of every
maxima mail. This would explain why I always received the welcome mail when subscribing to a maxima list, but nothing
more. I did receive the two mails you sent me CC from the list, though.

My guess would be that in order to build the blacklist your blacklist
provider won't use the mails that are sent to real users, except perhaps
if the user's mail accounts are hosted in a partner firm whose Eula
allows them to provide a blacklister with their user's data. I also have
heard that some blacklist providers scan mails that end up in
no-more-used old mail accounts. Since sourceforge adds Spam to most of
the mails they send out and some of their mailing lists will end up in
mail accounts no one has cared to unsubscribe for this might explain why
they ended up blacklisted while I until now didn't.
