Nonstandard SMTP line terminator

Got a strange problem.  Not sure if it is in sendmail, procmail,spamassassin, or clamav.
I have users that send E-Mail to a several different domain names that recive an error.

Maillog Excerpt:

Aug  7 08:37:29 mail sendmail[22572]: k77DUfS2021856: to=<Email Protected>, ctladdr=<Email Protected> (557/12), delay=00:00:26, xdelay=00:00:04, mailer=esmtp, pri=134786, relay=Servername Protected. [<IP Protected>], dsn=5.0.0, stat=Service unavailable

I have a reject message from one of these examples:

   ----- The following addresses had permanent fatal errors ----- <Protected EMail Address>
    (reason: 550 Requested action not taken: Nonstandard SMTP line terminator.)

   ----- Transcript of session follows -----
... while talking to <Protected Recipient Server Name>.:
>>> DATA
<<< 550 Requested action not taken: Nonstandard SMTP line terminator. 554 5.0.0 Service unavailable


I am noting this with several domain names that we send to.

We are using Sendmail with Procmail, dovecot for POP/IMAP, spamassassin with Razor, Pyzor, and DCC, and ClamAV.
