Limit external access to internal Dirsto group

[sAndeTri]

I have a distro group in exchange, That I want to assing an email address to so an external account can use the distro group. The problem is the external account is a service whos email address will change everytime mail is sent. Is there any way I can wild card it down to the domain?

What?

Can you explain a different way?

You have a distribution list that you want someone outside the company to use? So Jo@externaldomain.com can email DistyList@YourDomain.com from different email addresses every time?

Interesting setup. Why not just leave the disty list as default to accept emails from everyone?

The distro is to my entire company so we want to lock it down. but yes. thats what we want to do. We ant list@mycompany.com to except mail only from email address at @someother.com though exchange

Ah. OK. I don't know if there is a way to do that. All my Exchange servers have the group wide disty lists open to all and we've not had a problem yet.
