I can't seem to get any email to go to addresses outside of our domain using Eudora 5.1. When attempting to send messages we receive a message saying "AUTH CRAM-MD5" and then a message stating that "Server gives reason: 553 The specified domain is not in the list of allowed rcpt hosts 5.7.1". I spoke with our email provider and they said that they've upgraded some things to prevent blacklisting and that they don't support CRAM-MD5. The mail providers "fix" was to get rid of Eudora or use someone else to send mail. Since my boss is set on using Eudora and I don't want to pay someone else to send my mail, is there anything else I can try?
