I'd like the recursion limit raised from 20 to 50 by default if there's 
no objections. Thanks in advance.

I object.  No argument has been provided for why this is needed, except
by you, and your mechanism is fundamentally unsafe.  All that's needed
to break your setup with a limit of 50 is more URLs in a message body.
I will not be a party to you deluding yourself with feel-good
improvements.

Fix your setup, or accept the limitations of it which were pointed out
to you, by me, when you first talked about it.

-Phil

I've written the NewStuff entry for this change.  On the second attempt, I
think I have it correct.  Erk.

If anyone wishes to test, the DNS node txttest.test.globnix.net contains two
TXT records, per Simon's example.

Amusingly, my warning/reminder in NewStuff that DNS doesn't guarantee ordering
was validated on my very first test.

I suggest the limit stays the same, as increasing it may cause problems 
with existing installations depending on it (or without resources to cope 
with the drastic increase).

Instead, I suggest Marc supplies a patch that makes this tweakable at a 
build-time, so he can incorporate his preferred value into his own build 
processes.

Good suggestion going forward (could this be made a run-time config?), 
but even with a patch its not going to make 4.72

In any case a bugzilla entry should be opened for tracking.

	Nigel.

I agree; far to late to bring to the 4.72 table.

Good idea.  Marc, file your request at http://bugs.exim.org/ if this issue 
is important to you.

Jethro.

[Bug 992] New: Bug in $h_subject: decoding

------- You are receiving this mail because: -------

http://bugs.exim.org/show_bug.cgi?id=992
           Summary: Bug in $h_subject: decoding
           Product: Exim
           Version: 4.71
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: bug
          Priority: medium
         Component: String expansion
        AssignedTo: nigel <at> exim.org
        ReportedBy: lexore <at> gmail.com
                CC: exim-dev <at> exim.org

Exim do not decode $h_subject, when it coded in quoted-printable form.
And do not decode $h_subject (or decode only last line), when $h_subject is
multiline and coded in base64 form.

I found it, when i write a script, which work with variables:
h_to, rh_to, h_from, rh_from, h_subject, rh_subject.
h_to and h_from correctly decoded from quoted-printable, or base64, but
h_subject - not.

I don't tested h_to and h_from for multiline base64.

I write settings:
acl_smtp_data = acl_data

While I didn't check the code, I would assume that it's possible to 
change a "2" into a "5" before compiling. Thus this looks like a far too 
disproportinal change to me, both for Marc as for others who would have 
to adapt build framework, code and documentation.

Besides, this is a good example why the current development status of 
exim isn't as problematic as it has been stated here before (by few 
individuals). Exim is stable and functional. Everything that might be 
needed in addition is more or less questionable and there are many 
reasons for objecting its implementation. In addition to that, there are 
people who do care for implementing fixes and the still outstanding 
documentation.

This looks very much like a problem we've seen reported from Russian users
before: namely, that there's some software common in your part of the world
which is encoding quoted-printable text which is too long and violates RFC
2047.

If you add this to the main section of your Exim configuration:

  check_rfc2047_length = false

does the problem go away?

Thanks,
-Phil

God-damned!
It works.
Now all subjects are decoded.
Thanks.
I am sorry for a false bug.
