...but it's been a long long time since I've looked at this.

Look at:  Server Configuration Settings document -> MIME -> Advanced -> Advanced Outbound Message Options

What is RFC822 phrase handling set to? Try:  'Use CN as phrase'

Hi,

Thanks for the suggestion.

I checked the setting and it was "Do not add phrase".

I changed it to "Use CN as phrase", restarted the server and checked.

Unfortunately, I still get the 3 different formats, one for internal users, one for external contacts and one for my personal contacts.

Can you please advise?

I probably shouldn't have jumped in, because i didn't have a tried & true answer - but i thought i had an idea!  :-)

It appears that setting 'SMTP allowed within the local internet domain:' (Router/Basics tab) should (might?) do that.

You'd need to make sure that all servers have the SMTP listener configured, and 'Servers within the local Notes domain are reachable via SMTP over TCPIP: Always'

I played with this years ago, but had a bug ->  http://www-01.ibm.com/support/docview.wss?uid=swg21108473

and never tried again. But this link seems to indicate that it should work...

No issues Mark.

Thank you for your suggestion.

I will see if we can try it...
