Exchange 2003 email issue

I trying to send an email from my gmail account to my company distribution list (email address) so I can send one email from my home and it will automatically go to the poeple added to that distribution list..

I checked the distribution list and it has the ticket as everyone (not authentication) but it keeps rejecting this email. I tried the same email internally and it works fine..

DOes this mean Exchange 2003 doesnt allow externall poeple to email distribution lists..

It can be a spam filter or sec gateway settings.

Sometime gmail mail is marked as positive for spam so maybe your server denies it.

Per default I think only e-mail addresses that is members of the distribution group can e-mail the distribution group. You can set the restrictions by following this guide.

Use the "Only from" in step 5 and set the users you want to be able to mail your group. Be aware of the security aspect though because you dont want just anyone to spam this group.

Can you send an empty email, i.e. no text in the body, from gmail?

What happens if you create a new distribution group for testing and send it an email from gmail?

Does the distribution group accept any outside email? Try hotmail and some other corporate email address.

Not all distribution groups can receive e-mails unless they have an internet e-mail address. If you are using the e-mailing the account withion the company, it does not necessary uses e-mail address.

I suggest you to check your Active Directory if you are the admin or ask an mail admin for that Distribution group and make sure that has an internet e-mail address (example:

Also, it will help if you post the rejected NDR message for us to review.
