[OT] GPG Signatures

[Arthur Dent <mi...@blueyonder.co.uk>]

Hello all,

I have had quite a lot of trouble getting my posts through to mailing
lists (this one and others) lately. More often than not they simply
never appear which makes me wonder if there is something wrong with my
mail set-up (I would be grateful if someone could look at this one a let
me know if I am triggering any rules...)

Then today I received a bounceback message from a member of this list to
a message I posted (successfully) 9 days ago. The gist of the bounceback
is that my GPG signature was considered "unsafe". Now, I routinely sign
my messages (not this one!) because I think it is good practice, but
could this be at least part of the reason why my mail doesn't get
through?

I attach the relevant parts of the bounceback message below. Note, it
appears that it is something called "Firebox" that is doing the
rejecting for this particular member and is therefore OT here, but I am
baffled...

Thanks in advance for any suggestions...

If you posted to this list and that member bounced to you then it is 
*their* software that is not correctly set up.
I see many people signing on this and other list, there appears not be a 
problem.

nothing bad (dkim verified and spf pass).

systems that send bounce to addresses found in headers are broken by
design. if they should bounce, then they should use the envelope-sender.
I just (temporarily?) blacklisted 219.88.242.59, as I received 19
bounces between 7:25 and 7:40 this morning.

yet another hopelessly silly filter! GPG is of course a good practice.

there's nothing to do.

What does the reject message say?

No.  There is a subscriber rewriting the recipient address to an 
invalid one.  The bounces are incorrectly sent to the author of the 
message instead of the sender.
