I am having a problem with sendmail. I am not very fluent with the sendmail errors but I am getting.....
220 mail.bellsouth.net ESMTP server (InterMail vM.5.01.06.05 201-253-122-130-105-20030824) ready Thu, 20 Nov 2003 02:50:29 -0500
250 Sender <firstname.lastname@example.org> Ok
RCPT TO: email@example.com
550 .net 003: you are not allowed to send e-mail to <firstname.lastname@example.org>
503 No recipients specified
500 Command unknown: 'IT'
where xxx are valid email addresses
Any help would be greatly appreciated.
