We're in the process of transferring our Autoresponder package (ARP) from a shared server to a new standalone server.

What we're finding is that when we send text format emails from the new server, they're arriving with additional line breaks inserted between lines, which makes the formatting look horrible.

When we switch from Sendmail as a mail transfer agent to SMTP, this problem goes away, however SMTP can't handle the volume of mail we're throwing at it (it inserts only 10% of the mails into the mail queue.)

Has anyone run into this and, if so, what was the solution?

Thanks!
