Hi,
We are unable to send emails via our Exchange server using Pop3. The NDR is
- The following recipients could not be reached: 'user@domain.com' 554 5.7.1
: Relay access denied
Exchange: Pop3 & SMTP Virtual servers are configured
Outlook account settings are:
Outgoing server is set as 'my outgoing server (SMTP) requires auth' and 'log
on to incoming mail server before sending mail'
When i click Test Account Settings it's successful (eg. Send test email msg
- completed)
I have tried every other Outgoing server option unsuccessfully
I am able to telnet to the outgoing server address on port 25
Does anybody have any suggestions? Thanks
