ok look at /etc/resolv.conf on the email server
i use :
domain scom.ca
search scom.ca
options timeout:2
options attempts:1
nameserver 10.220.0.2
nameserver 10.220.0.18
nameserver 10.220.0.6
nameserver 10.220.0.16
this gives the basic's on multiple dns server's and how to handle timeouts
note my name servers are internal to my network (the 10.220.0/24)
however on the email server you should throw a 8.8.8.8 in as a backup
as for a windows desktop it is more flexable on timeouts - fyi
Happy Monday !!!
Thanks - paul

My apologies, Paul! You are correct re: dashes not dots. I cut/pasted
without paying attention, I'm afraid. 🙁
I originally ran dig on my desktop through my local ISP's DNS as a
cross-check on the domain and did get
bcs-hants-sch-uk.mail.protection.outlook.com. Also on the mail server
(in terminal) with same results, although it did take over a second to
resolve. On another server it took approc 200 ms. So I'm now wondering
if the problem is resolution time.
Is there a time-to-wait value I can set? Can't seem to find one either
in ubound nor postfix.
Forgot to mention, I get several mail rejections over a short space of
time (a client is sending out to his address book).
Ubound is set to ipv4 only.
