The correct NSmail settings to use for Outlook can be found here:http://www.networksolutions.com/support/st...p-instructions/
The issue I'm having is why do incorrect settings still work
On numerous client machines (at different locations), the Outlook SMTP outgoing server it set to: mail.company.com instead of smtp.company.com (like the NS instructions say). On other client machines, SMTP authentication is not applied; however the NS instructions say you have to. On other machines, I have both outgoing server set to mail.company.com (instead of smtp.company.com) AND smtp authentication not used (instead of using authentication that match incoming mail server).
There are well over 500 client machines in 20 different locations. These Outlook settings were configured a few years back before I got here. The only reason why I bring it up, is that on a few client machines (over time), the end users are unable to send email; however once I correct the settings, it solves the issue. When trying to explain these "proper" settings to the old IT dogs, I'll get replies like:That’s inconclusive. Considering that it’s been working for the last 3 years on 4 different operating system and at least 5 different computers. My settings as of today: (picture of Outlook) showing incorrect settings.
Can someone shed some light on this issue? I even pinged both servers, and the mail.company.com and smtp.company.com are both different IP addresses. Did NSemail settings change from a few years back?
