spamassassin-3.4.0_11 and p5-Net-DNS-0.76 worked as expected. After upgrading to p5-Net-DNS-0.77 I ran into an issue that looked similar to the one reported above. spamd couldn't be daemonized at start-up (timed out). After some investigations I found the reason why spamd didn't start after upgrading to p5-Net-DNS-0.77:

/etc/resolv.conf
	nameserver	1.2.3.4		# some comment
	nameserver	8.8.8.8		# another comment

That has been accepted by p5-Net-DNS-0.76, but for p5-Net-DNS-0.77 I had to remove the comments:

/etc/resolv.conf
	nameserver	1.2.3.4
	nameserver	8.8.8.8

After removing those comments spamassassin-3.4.0_11 and p5-Net-DNS-0.77 run as expected.

Is this a bug or a feature?

Thanks and regards,
Michael
