[Mailman-Users] Re: I'm on Microsoft's blocklist again!

2021-12-07 Thread Paul Moore
My experience is that MS uses its own system and I do typically, not 
always, find my server on other RBLs when I'm on MS. Currently I'm 
having issue with Cisco's Talos system even though I'm not on any from 
https://multirbl.valli.org or MSToolbox.


This is where I deal with MS if you haven't seen it before.

Hi,


Just over two weeks since I found myself on Microsoft's blocklist and 
was manually removed, I find myself back on their blocklist again. 
Possibly coincidentally, this morning MXToolbox informed me that 
Linode has apparently found itself back on Uceprotectl3. Does anyone 
know if Microsoft considers that particular blacklist when deciding to 
blocklist an IP? Naturally, I've submitted a deliverability support 
ticket, and will probably have to wait several hours for the result.



As always, I'm not doing anything wrong (that I know of at least). 
Even if someone had hacked my server, my hypothesis is that they'd 
have to be a very careful and methodical hacker if their aim were to 
get me blocklisted by Microsoft and only Microsoft. If my server were 
spewing out spam, I ought to be hitting Spamhaus/SORBS/etc. spam traps 
left and right. Trust me, one time I was hacked, my server was sending 
out spam and I didn't know it, and I quickly found myself on Spamhaus 
XBL.



Any thoughts?


Thanks,


Jayson

[Mailman-Users] Re: emails sitting in postfix mailq a long time

2022-01-25 Thread Paul Moore
When my mailq get hundreds to thousands stacked up, all email slows to a 
crawl.


Is your DNS setup correctly? Can you confirm the NLx.shaw is able or 
not able to be resolved?

It looks like the user doesnt exist so yes 99% sure it is a bounce.  Just for 
some reason this list is really bad at cluttering the mailq.

We are still getting delays of hours on odd emails in other lists which I cant 
fathom yet but it is not this impacting I think?

Hi,

trying to figure out why there are a lot of these in postfix's mail queu,

75D752B3E0*  415295 Tue Jan 25 12:38:50  MAILER-DAEMON
   xx-bounces@lists.xx

Are these bounces back into mailman?

They could be. They also could be spam sent to the
xx-bounces@lists.xx address, but the MAILER-DAEMON sender makes
bounces more likely.

The asterisk says the message is active. Whats in the mail.log for
these? E.g.

grep 75D752B3E0 /var/log/mail.log

[Mailman-Users] Re: Dream Host -- Google Yellow Boxes -- GNU Mailman

2022-08-05 Thread Paul Moore
I've noticed this issue popping up recently on a few domains I host, not 
mailman necessarily. Gmail has changed something on their end. I've told 
those affected to have the gmail users complain about these notices.

Dream Host also recommends enabling Munge From in the administrative
