Display name incorrect

[portscanner]

I created an account and set:
First Name: George
Middle initial: J. (note the period)
Last Name: Smith

This created a display name of (with the auto box checked)
George J.. Smith (note the two periods after the J)

I changed the middle initial to be
Jr (note the R and no period)

This created a display name of (with the auto box checked)
George Jr. Smith

This also updated the name in the global address list.

but....

Any email created using the web interface or using Outlook (with the zimbra connector) has a from line of:

George J.. Smith <george@mydomain.com>

Also Outlook displays the "J.." at the top of the folder list.

Going back to the administrative tool and removing the check from "auto" box and changing the Display name to just "George Smith" does not change the name put on the from line.

Any suggestions?

I am running 7.1.2_GA_3268 Network Edition.

zmprov ma george@mydomain.com zimbraPrefFromDisplay "George Smith Jr."

I discovered there is a extra field of information (not available through the web interface) that allows you to set the "From" name to be different from the "Display Name"

To see the current value you can:
zmprov ga george@mydomain.com | grep PrefFromDisplay


Dont know how/why it is not kept in sync with the Display Name, but I got it fixed.
