Thanks for that.  The service imap-login line above is in the file 
/etc/dovecot/conf.d/10-master.conf.  I don't know if that is standard 
for version 2 or something that Ubuntu created.

The Ubuntu installation has this line in the /etc/dovecot/dovecot.conf file;

!include_try /usr/share/dovecot/protocols.d/*.protocol

That directory contains one file;

dovecot-imapd.protocol

and it contains one line;

protocols = $protocols imap

So I am assuming that it is adding imap to the protocols in the 
environment variable $protocols somehow?

dovecot -n yields;

protocols = " imap"

I did get TBird to retrieve mail from port 993 using SSL however.  Will 
it work without a protocols = imaps?

Thanks,
