[courier-users] service unavailable

[Dan R. <dr...@dr...>]

I had courier 0.32 working happily on a Redhat Linux 7.0 box.  I've just 
tried to upgrade to Redhat 7.1 and Courier 0.33 and am having two problems.

First, the ESMTPD service keeps giving me the error:
	450 - Service temporarily unavailable.
When I use type:
	echo "To: postmaster" | /usr/lib/courier/bin/sendmail
I get a bit more info, but not much:
	450 - Service temporarily unavailable.
	450   Headers specify no receipients.
Any idea what's going on here? An old thread suggested checking aliases 
permissions - I've done that and they are the same as on my old box. 
-rw-rw-r-- root root   aliases.dat.

Second, Webmail won't let me log in - it keeps giving the error "Invalid 
User Name or Password" which it isn't.  Courier POP validates the account 
without a problem.

I think it's likely that I made a tweak in an old config file that I'm not 
finding again, but any advice would be valued as gold.

Thanks!
