There are only two daemons, actually: the MTA, and the client mqueue  

The separation was made because sendmail used to run as a single,  
setuid-root executable, and has had a rather infamous security  
history as a consequence.  If you want sendmail to be running and  
listening on port 25 as a MTA, you need to set the sendmail_enable/ 
sendmail_outbound_enable to YES.

The standard period for a DNS timeout is anywhere up to about two  
minutes, depending on how many resolvers are configured in /etc/ 
resolv.conf.  It's possible to tell sendmail not to use DNS, and  
avoid this timeout, but normally people run mailservers only on  
machines with working DNS and a sensible hostname.  This isn't a bug,  
it's just an assumption that sendmail makes which is typically  
appropriate, but not for the case of a random client machine without  
working DNS....
