Once I have the names in the distribution list and send out the E-mail will the E-mail go out one at a time and is there a limit to how many in my distribution list.
I don't have access to an Outlook at the moment but I believe they send separately.
The limits for number of connections and recipients per email vary by ISP.
I see that Bell South limits by size (10MB) and that they might try to bill you $5 per spam incident, but I do not see any other limits publicly posted about their service.
If you are using another providers SMTP outgoing mail servers I can try to help you look up their limits.
