Pkg exim4 users - May 2007 - What does exim4 need after the network connection changes?

Hi,

I use my laptop with two different mail setups, depending on the network
I''m in.  To achieve this, I change the target of the symlink
/etc/exim4/update-exim4.conf.conf, and call "/etc/init.d/exim4
restart"
afterwards.  

This usesd to work fine in sarge, but now in etch, it seems that this is
not enough to make exim play nicely.  The problem is that sending mail
(from gnus) takes very long after the network switch (and up to the next
reboot).  I tried to quit gnus and emacs to make sure that the problem
is not on the side of the MUA, and it persisted.

I observe the same behavior when the interface is up and a route
configured, but there''s actually no connectivity (e.g. because a WLAN
connection was dropped).  I don''t complain in that case, just as a
point
of information.

What can I do to make the switch smoother?

Regards, Frank

It should. I am not aware of any changes between sarge and etch that
deliberately break this behavior. And in fact, my notebook changes
network all the time, and exim behaves just fine.

Please try delivering a message by piping it to exim -d and see what
takes so long.

Hm, can I just take a mail buffer from Gnus (with To:, Subject:, Date:,
and From: headers and some body text), or do I need anything else? 

And then I do

exim4 -d < mail.txt 2>&1 | tee eximtest.log

Okay?

Usually echo fasel | exim4 -d some_address at domain.example will do fine.

It took me a while until I encountered the problem again (I''m at the
university less often, they no longer paying me...).  I did (as root)

echo fasel | exim4 -d frank at kuesterei.ch

and that was fast, so maybe it''s still emacs/gnus...  I have no ideay
how to really check that, except that once more I''m now going to exit
emacs.

I suspect a DNS issue. Your DNS server might have cached the result
from the previous call, so the debugging was fast.

I am kind of out of ideas as well.
