A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

  maemo-community@maemo.org
    SMTP error from remote mail server after RCPT TO:<maemo-community@maemo.org>:
    host mail.maemo.org [213.128.137.23]: 550 5.7.1 <maemo-community@maemo.org>:
    Recipient address rejected: Mail appeared to be SPAM or forged. Ask your Mail/DNS-Administrator to correct HELO and DNS MX settings or to get removed from DNSBLs; MTA helo:
    mailscan1.extendcp.co.uk, MTA hostname: mailscan38.extendcp.co.uk[176.32.230.32] (helo/hostname mismatch)

------ This is a copy of the message, including all the headers. ------
<snip>
An overly aggressive spam filter? It seems to complain about the mismatch between helo and hostname, as if anyone should care.
E-mail systems do care about such things. The HELO address should resolve the same IP the MTA is connecting with. I assume you don't own extendcp.co.uk, but it doesn't seem to be doing the right thing.

See RFC2821 (item 4.1.1.1).

I suppose our techstaff set-up policyd-weight on the postfix server, which checks this sort of things. In principle it's a good thing as the maemo mailing lists were receiving lots of spam.

Chemist & co. care to comment on this?

EDIT: I've sent a note to techstaff asking for clarification.
