	We need to know:

	- what mail domains is postfix configured for - if in doubt:

	postconf -d mydestination
	postconf -n mydestination
	postconf -d relay_domains
	postconf -n relay_domains

	- a sample from the mailq output when the problem happens, say:

	mailq | head -100

	Then we can begin to troubleshoot.
