How do I correct error message:4.5.3. Too many recipients?[^]

It states that:

Quote:
The easiest way to prevent this message from popping up is to create distribution lists with a reasonable amount of e-mail addresses,less than 25 recipients if possible, although your server may allow between 50 - 75 recipients on each list. You can find out the limits for sending e-mails by contacting the mail administrator or your ISP. By saving a number of distribution lists with less than this number of contacts, you should avoid receiving this error message the next time you send mass emails.
