Here comes the third part of compatibility patch for sendmail.
* Introduced new safe_getdomainname() -- will it be useful?
* Fixed SEGV if sender address is missed. Should snoop for sender address in mail headers?
* More compat: use HOSTNAME instead of HOST when no server is explicitly specified.
* crond: fixed mail recipient address.
