here is the issue
- W2K/Exch 2K box
- changed ISP's about a couple of weeks ago
- ensure that all MX records and A records are up to date
at ISP for my company's domain
- check domain and mail server for resolve at
www.dnsreports.com and www.network-tools.com
- everything looks good
- have symantec anti-spam protection and GFI Mail
Essentials installed as well
- cisco router with ACL's
- sonicwall VPN concentrator
- i have one user who can not recieve email from at least
8 different domains ( user was able to recieve these
emails before ISP changed )
- I asked IT guy apparently blocked domain to send email
to me and it bounced
- he says no NDR value/message other than ".....delay in
delivering message due to network congestion or server is
offline.
CAN ANYONE HELP WITH THIS ONE. I am totally at a lost here
with this one, thanks.
