When using a laptop it is normal that there are some changes in
resolv.conf during the live, for example:

boot time: no network available
start of PPP over UMTS: resolv.conf from provider
start VPN to connect to company: resolv.conf from company

it seems that sendmail is not aware of such changes in the resolv.conf
and always get stuck with the old DNS and ofc does not work on incoming
mails (provided by fetchmail). A restart helps, but is there some better
way to let sendmail switch to the new DNS environment when resolv.conf
