Sending an email to LDAP/AD group - Mail Alias is not a solution

@davidep

I just attempted to send from Tbird connecting to Nethserver using SMTP (465).
the 10.xx.xx.x address is the UCS server, so it looks like NS is attempting to deliver the mail to the UCS server instead of locally

I really hope I have misconfigured something and you can suggest I try something different.

[root@sparky html]# db accounts show instructors@sgvfr.com
instructors@sgvfr.com=pseudonym
    Access=public
    Account=SGVFR-INSTRUCTORS@sgvfr.lan
    Description=ALL-SGVFR-INSTRUCTORS
[root@sparky html]#

[root@sparky html]# db accounts show members@sgvfr.com
members@sgvfr.com=pseudonym
    Access=public
    Account=SGVFR-MEMBERS@sgvfr.lan
    Description=ALL-SGVFR-MEMBERS
[root@sparky html]#

the groups on the UCS server contain the email address's of the members.

Any thoughts or suggestions on what I can try??

Thanks!
