Topic: How to restrict email groups within Horde to those with local email accounts?

[tstokovaz]

I want to restrict our email groups to be used only by those who have email accounts on the local SME server. My goal is to reduce spam and to keep the use of these groups restricted to those who need them. Example jblow@company.org can send to staff@company.org because he has an account but ImaSpam@xyz.org is blocked from sending to staff@company.org because she has no local account. Is this possible?

It is not possible. Qsmtpd does not have such a feature. (Webmail is just client and therefore not involved)
I choose hard to guess groupnames to avoid receiving spam.

Are you trying to do the same thing as this person?

No, I want our folks to be able to send mail as they need to, in or out, I just want the groups to only be used by our email users with valid email addresses within our organization (ie on our webmail server). I've been told this is  not possible so I'll just work on other options. Thanks
