[Wolves] Host look up problem with email

[Wayne Morris]

Hi,

My email server correctly sends mail sent to it by smtp from clients on 
the Lan, but mail generated on the same machine
by a web client is held in the out queue with 'host lookup not completed'

As DNS seems to be ok (other mail is sent, web browsing from this 
machine works, incoming mail is correctly checked for DNS entry),
I'm baffled as to why this is happening.

Any ideas pls.

Wayne
