SMTP error from remote mail server after RCPT

[Matthias Apitz]

Hello,

This is perhaps not a problem with mutt itself, but maybe some expert can
lend me a light.

I'm member of a group and as this I do receive mails sent by others to the addr
jw%leserini-***@gmx.de. But when I reply, the mail gets rejected, see
below. How is this possible that the originator can send this mail to jw%leserini-***@gmx.de
but I can not?

Thanks

matthias

This rejection is the result of the "percent hack" implimented on
sendmail, postfix and, perhaps, other mail servers.

Nothing to do with Mutt.

Yes, it's a bit off-topic. And, thanks for the pointer to that "percent hack"
I will look for its explanation. Interestingly the mail is accepted and
delivered when I send to

jW-Leserini Verteil <jw%leserini-***@gmx.de>

Thanks again
