bad link/anchor in the Postfix HTML documentation


On <a href="" title=""></a>
there is a link "fingerprint", with the URL:

<a href="" title=""></a>

However, on this web page, the client_tls_fingerprint anchor doesn't

postdrop hangs until reboot: warning: mail_queue_enter: create file maildrop/...: Permission denied


FYI, I've just reported the following bugs in the Debian BTS
for postfix 3.2.2:

<a href="" title=""></a>

In summary, there's one problem that is hardly reproducible,
and an incorrect error message.

When I tried to send a mail with mutt (via the usual
"/usr/sbin/sendmail -oem -oi" command), it was hanging, and ps showed
that it was due to postdrop, which was hanging. There was no such
problem when I sent a mail 20 minutes before.

mime_header_checks physical lines vs logical headers


With postfix 2.9.3-2~12.04.3 under Ubuntu:

The header_checks(5) man page says:

Note: message headers are examined one logical header at a time,
even when a message header spans multiple lines. Body lines are
always examined one line at a time.

But after doing various tests on mime_header_checks, it appears
that headers are examined one physical line at a time (instead
of logical headers).

I wonder whether this is a documentation bug or a buggy behavior
of postfix, but considering logical headers would be more useful
in practice, IMHO.

header_checks rule that doesn't work

I've received a mail having:


I wanted to reject such mail with

REJECT GB2312 in headers

in header_checks.pcre, but this didn't work. I don't understand because

postmap -q - pcre:/etc/postfix/header_checks.pcre < the_message

says that the rule applies on this line.

Any idea?

serious bug with check_client_access


It seems that I've found a serious bug in check_client_access
(or something is missing in the documentation).

A message was blocked with the following in the log:
