Dovecot error when sending email on port 993
I'm trying to setup my Postfix + Dovecot email server with my email client. POP (port 995, SSL) works great. But when I'm trying to send mail over SMTP port 993, I get this error:

I think the connection to the server is working...so is this an authentication problem? What is an "incorrect greeting?"

Your email client is trying to talk SMTP protocol, but the listening side is talking IMAP.
Looks like Dovecot is already listening on port 993.
To my knowledge, Dovecot is not an SMTP server.
As it has been said you are using an imap server as smtp server and this cannot work. Postfix should listen to port 25 for plain text /starttls sessions...
What is the output of
netstat -lnp
???

Server name: bill
Port: 993
User name: bill@....
Authentication: Password
Connection security: SSL/TLS
Your postfix is listening on port 587. Set your email client to use that port in ssl.
That works, the "incorrect greeting" error message is gone!
