I am installing sendmail for the first time. I sent email from one user id on one workstation to the other workstation. The source workstation is running the standard solaris sendmail and the destination workstation is running 8.9.1 with a default configuration file.
When sending email from the source workstation, I get my email returned with a "Remote Protocol Error". If on the destination file I change back to the standard sendmail then the email makes it there.
How can I fix this ?
