IPV6 error in exim, though disable_ipv6=true

[Privacy]

Hello,

I am trying to set up exim4 to use my gmail account. But mail is queued
and is never sent because the log says:

2014-04-10 22:48:05 Start queue run: pid=12623 -qff
2014-04-10 22:48:05 1WYK8P-0001YZ-Ix IPv6 socket creation failed:
Address family not supported by protocol
2014-04-10 22:48:05 1WYK8P-0001YZ-Ix gmail-smtp-msa.l.google.com
[2a00:1450:400c:c03::6c] Address family not supported by protocol

I have Exim 4.80 with support for
crypteq iconv() IPv6 GnuTLS move_frozen_messages DKIM

In /etc/exim4/update-exim4.conf.conf, I have at the end:

disable_ipv6='true'
dns_ipv4_lookup='*'

I have reloaded my configuration and restarted exim4:
# update-exim4.conf
# service exim4 restart

Restarts fine, but mail gets queued, and telling it to process the queue:
# exim -qff

results in that log error in /var/log/exim4/mainlog.

Can somebody help me out ?

Thanks!

PS. If that helps, I'm on a Raspberry Pi, Raspbian.

This sounds like http://bugs.exim.org/show_bug.cgi?id=1374
which is unresolved. Please add your info there.

Check if the option made it to the configuratiion:

exim -bP disable_ipv6

should tell you the used value. Maybe it helps you further debugging
this issue.

Hi Heiko & list,

Thanks for the tip.

exim -bP disable_ipv6

This tells me:
no_disable_ipv6

which I guess is not good :(

However, I did a few things:
- I had both a /etc/exim4/conf.d directory (split config) and a
exim4.conf.template (unique file). I removed the conf.d directory to be
sure it'd read the unique config file.

- The config file is named 'exim4.conf.template'. Is that really
correct? In doubt, I duplicated it to exim4.conf.

+ I have a update-exim4.conf.conf file.

Now, restarting exim4 I have in the logs:

2014-04-14 22:43:43 exim 4.80 daemon started: pid=32736, -q30m,
listening for SMTP on port 25 (IPv4)
2014-04-14 22:43:43 Start queue run: pid=32741

that's good.

Then I do a exim -qff and the logs say:

2014-04-14 22:44:45 Start queue run: pid=300 -qff
2014-04-14 22:44:45 1WZ4qE-0005vb-JJ Unfrozen by forced delivery

So, this looks different, doesn'it it? Why is it "unrouteable" ?

I do not know the Debian way of Exim configuration. Are these settings
already there, or did you invent these options?

Ooops. Under Debian Exim tries to read

/etc/exim4/exim4.conf
/var/lib/
/*autogenerated* (I do not exactly remember that name)

in that order. The first match wins.
If you copied the exim4.conf.template to exim4.conf you may get
unexpected results. I think, the exim4.conf.template isn't a complete
and correct Exim configuration. But maybe it's a syntactically correct,
but incomplete configuration. (/dev/null is a correct but incomplete
(depending on the purpose) Exim configuration too.)

Using "exim4 -bV" tells you the configuration file used.

Probabably because of 
. see above, inapprobiate/incomplete
configuration.

You really _really_ should read Debian's documentation on how to manage
their Exim configuration files, which explains how the pieces fit
together. The same applies on Ubuntu or any other Debian derivative.

$ gzip -dc /usr/share/doc/exim4/README.Debian.gz | less

You want "2.1.6. Using a completely different configuration scheme" and
sub-sections thereof.

You can probably recover deleted configuration templates from apt/dpkg.

Ok - I had messed up my previous exim4 configuration, so I fully
uninstalled, removed configuration and re-installed exim4.

I am trying to get exim4 send my email to a gmail account.
I have followed this, and am using unsplit configuration:
https://wiki.debian.org/GmailAndExim4

$ echo "blah" | mail -s "test" ***@gmail.com

The logs unfortunately say:

2014-04-16 21:39:58 1WaVgc-0002z2-BS IPv6 socket creation failed:
Address family not supported by protocol
2014-04-16 21:39:58 1WaVgc-0002z2-BS gmail-smtp-msa.l.google.com
[2a00:1450:400c:c03::6d] Address family not supported by protocol

I add

disable_ipv6='true'

to /etc/exim4/update-exim4.conf.conf

Then, update-exim4.conf, invoke-rc.d exim4 restart

And, I get the IPv6 log again... :(

If I check this, it looks like my disable_ipv6 command was not taken
into account:

$ exim -bP disable_ipv6
no_disable_ipv6

The configuration file exim4 uses is:

$ exim4 -bV
Exim version 4.80 #3 built 13-Jan-2013 05:36:41
...
Support for: crypteq iconv() IPv6 GnuTLS move_frozen_messages DKIM
...
Configuration file is /var/lib/exim4/config.autogenerated

But after reading the doc ($ gzip -dc
/usr/share/doc/exim4/README.Debian.gz | less), I think this is normal
and I should not touch this configuration file.

Yet, the fact is that I can't send email, and that it complains about
IPv6 and I don't know how to cope with that...

So... check this file for mentions of "disable_ipv6?"
Did yours make it into there? Are there multiple, conflicting ones?

disable_ipv6='true'

And, I get the IPv6 log again... :(

update-exim4.conf.conf is *not* a general purpose exim configuration
file (and I don't believe any part of documentation suggests that it
is). As it's name suggests, it is the configuration file for the tool
"update-exim4.conf"; the update-exim4.conf manpage documents the options
/ variables which will be parsed and used from the file.

If you want a directive to be included in the configuration, you need to
either add it to the relevant place in /etc/exim4.conf.template or to an
appropriately located file in /etc/exim4/conf.d, depending on whether
you've told exim to use split configuration. See
/usr/share/doc/exim4/README.Debian.gz and update-exim4.conf(8) for more
details.

Ok - indeed.

I tried to put disable_ipv6 = true in /etc/exim4.conf.template, and then
do a update-exim4.conf, but I does not know that option:

2014-04-17 20:24:17 Exim configuration error in line 887 of
/var/lib/exim4/config.autogenerated.tmp:
option "disable_ipv6" unknown

I also tried to manually add it to
/var/lib/exim4/config.autogenerated.tmp which of course led to the same
result.

So, "disable_ipv6=true" is not right.
Though I see here
(http://wordgraphs.com/post/5500/Gmail-error--Our-system-has-detected-that-this-550-5-7-1-message-is-likely-unsolicited-mail)
and here (http://bugs.exim.org/show_bug.cgi?id=1374) that people are
using it.

What's the right syntax for that command please? I have been unable to
see it in the doc...

That is the correct configuration directive. In a normal Exim config,
you'd just add it in the main section near the top of
/etc/exim/exim.conf. However Debian does this non-standard thing where
the config is split across several files and it constructs a real
config for you using those files. That "disable_ipv6 = true" directive
needs to end up in the main section of the final Exim config. I'm
guessing that means you need to put it in one of the files in
/etc/exim4/conf.d/ or something? I use Debian myself, but the first
thing I do after installing Exim is an "rm -rf /etc/exim4/*" and then
create an exim4.conf manually.

FWIW, there is a Debian specific Exim mailing list where you might get
better help:

Ok, I found the solution. I am not using slit config, so not the conf.d
dir.
I put disable_ipv6 = true rather at the beginning of the file:

exim_path = /usr/sbin/exim4
disable_ipv6 = true

and it works. It accepts the configuration, and accepts the options.

$ exim4 -bP disable_ipv6
disable_ipv6

So, that's a first step at least.

But my emails aren't sent. For reminder, I'm trying to have them sent to

Yes, you're right. I hadn't opened the port on my firewal ;(

Then, I had an issue with exim4 not being able to open my
/etc/exim4/passwd.client -> solved by chown root:Debian-exim passwd.client

Then, gmail still wasn't happy and could not receive my credentials:

-> I solved this by this thread
http://ubuntuforums.org/archive/index.php/t-2090069.html

*.google.com:***@gmail.com:mypassword
*.gmail.com:***@fmail.com:mypassword

and that works, though to be honest I don't exactly know why just
putting smtp*gmail.com:***@gmail.com:mypassword does not work.

Anyway, now, I send my emails!
