[darcs-users] Tip for avoiding sendmail DNS errors (451 error)

I've had persistent but transient problems with darcs send - emails
failing to be delivered - and now I have found what may be the solution:
it turns out that sendmail doesn't notice changes to /etc/resolv.conf.
For the record, the solution is to restart sendmail
whenever /etc/resolv.conf is modified.

Obviously, this doesn't necessarily apply if you're using some other
sendmail-compatible program.
