Hi All, This is my first post to this group.
I have had a SBS 2000 installation running for a few
months now, but every now and again (maybe 4-5 times a
week) the outbound messages seem to get stuck in
the "destination unreachable queue".
Once one message gets stuck in there everything else
seems to pile up behind it.
All SMTP mail is forwarded to our ISP via smart host
setting (also tried with ISP's ip address instead of
FQDN).
The other error I get in the event log is event 4003 the
domain "whateveritis.com" is currently unreachable" .
This relates to the domain that I was trying to get an
email message to in the first place and doesn't seem to
matter what the email address is.
I can send a mail to an email address one day, and maybe
an hour later if I send to the same address that
succeeded before it goes straight to the destination
unreachable queue and locks up all other messages until I
restart the smtp service.
If I restart the SMTP service all messages are delivered.
I found this article on the KB 289808 but my question is
this. Have many of you SBS Admins out there had to do
this disabling 8 bit MIME? It seems quite complex and I
am just wondering if anybody else has had to do it.
Any other ideas would be gratefully accepted?
thx in advance
Andrew
