After much discussion and experimentation, I thought I had mutt sorted out.
I'm using a dial-on-demand internet connection and used Donncha's magic
sendmail configuration tool and all worked fine (until I tried mutt that
is!). There follows the sendmail.mc generated by Donncha's script after me
answering questions like "Do you want to queue your email" with "Oh yes
please!!"
Mail gets properly queued by most programs but when sending with mutt,
sendmail seems to do a DNS lookup on the target host even though the mail is
queued for later sending. I read the mail-queuing HOWTO and everything
mentioned there is in the sendmail.mc but it still seems to happen at times.
Could it be something like sendmail doing a lookup on "smtp.oceanfree.net"
once its TTL has expired in my DNS cache?
The only sendmail references in my mutt configuration are listed below. The
"sendmail_wait=-1" is supposed to return control to mutt without waiting for
sendmail to finish processing and no other sendmail stuff exists in
/etc/Muttrc or in ~/.muttrc
I've done the "m4 sendmail.mc > /etc/sendmail.cf" to build the config and
done "/etc/rc.d/init.d/sendmail restart" to reconfigure so I'm not
forgetting stuff like that or anything.
Any further ideas?
Thanks
Conor Daly
