Hi,

I have several desktop systems, and regadless of whether I leave exim4
unconfigured, or setup for local system use only, it takes quite a while
to start on boot.

I don't really know what the MTA is supposed to do on a laptop or desktop
system, but I've read that it shouldn't be uninstallted.  Is this really
the case?


It shouldn't be uninstalled since many daemons and system management
tasks report via email, and they expect to find an MTA to send the mail
with.

If your system isn't connected to the internet on boot, have you

configured minimal-dns? From 'dpkg-reconfigure exim4-config':

In normal mode of operation Exim does DNS lookups at startup, and when

Thanks for any suggestions,

Thanks, I tried that and it didn't help, but I'm not sure I know which of the
five types of setup choices really applies to me, and I'll have to read up
some more on that.

I have to say that  I'm actually only interested in using Debian as a desktop
system, and sort of feel like it is making me install a mail server.  I
wouldn't care if choosing "no configuration at this time" didn't cause
problems, but in my case it seems to be timing out on boot.

Thanks,

C



Theres always the option of disabling it all together.

update-rc.d -f exim4 remove
But, as others have said, its good to have a MTA running for notifications like cron, logcheck and others to go out. I would possibley install exim4-daemon-light, set delivery to local only, check to make sure your hostname is in /etc/hosts and set hosts in /etc/nsswitch.conf to: hosts: files dns
