[Dev] IMAP and SMTP accounts defined in external parcel

In fact the preferred method for MUAs to transfer mail to MTAs is using 
Submission (RFC 2476) on port 587.  Many sites choose to encourage the use 
of this port for authenticated mail submission (so they don't have to mess 
with doing it on port 25 of their MTAs).  It is true that port 25 is far 
more widely used for this purpose just because it always has been, but it 
is a good idea to support 587 also (and the procedures specified in 2476).

Let me humbly suggest that it is inexcusable to ship an IMAP server in 
2005 that doesn't support STARTTLS.  STARTTLS is the standard method for a 
reason.  The separate-port approach will unfortunately have to be 
supported forever probably, but it is just bad form to encourage it.
