We are using mailscanner as a mail/spam/av gateway and created a mailertable entry in sendmail to route all mail to the internal Scalix server. Everything appears to be working fine but the maillog on the gateway shows the error below when the message gets forwarded to the Scalix mail server? I have tried setting the mailertable entry to smtp and esmtp but neither appear to make a difference. I dont know if this is a sendmail or scalix issue?
scalixserver.mydomain.com did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA
