imap-ssl protocol error on mac os x
Shaheen
using imap-ssl. i've installed stunnel4 through macports and pointed
vm-stunnel-program at it. however, i still get the protocol error
"unexpected char (10)". i've seen reports noting this error happens
due to the use of stunnel3, but i've specifically pointed vm at the
full path of stunnel4. any ideas why this may continue to happen?

If you list buffers, you will find a buffer with a name like *trace of
IMAP...*. See what it says. Mine begins with the lines:
starting IMAP over SSL session Thu Aug 26 01:15:18 2010
connecting to imap.gmail.com:993
connected for fetch
Unfortunately, I have no idea how to debug stunnel connections.
One idea you can try is to set vm-stunnel-program to just "stunnel4" and make
sure that the program is on exec-path. I don't know if it will make a
difference, but it is worth trying.

Not sure, but maybe this helps:
Just two weeks ago I had similar problems with VM, imap and stunnel4
on Debian Linux, always the same error: "unexpected char (10)" and
nothing else worked.
It turned out that just installing the Debian stunnel4 package was
not enough, because the Debian package uses stunnel_4.22, a more
than two years old stunnel version, what already seems to be too old.
After I had compiled and installed my own stunnel_4.33 version from:
everything works fine now, no more "unexpected char (10)" errors.
Unfortunately I have no idea what the exact reason was why
stunnel_4.22 didn't work, but maybe you could try to compile
and install stunnel_4.33 on Mac OS X?

Uday: the buffer you describe has "SSL context initialized for service
stunnel" and then the next line reads "line 4: Each service section
must define two endpoints". After that, there is a line saying the
process exited. Note that this occurs after the connecting/connected
lines you mention. here's the full text of the buffer. any further
ideas?

Sorry, I should have included the next line in my earlier message. It
should should be of the form:
* OK Gimap ready for requests from ....^M
This is the first line of response that VM looks for in talking to an
IMAP server. Your connection terminated before reaching that stage.
Like Edgar, I suspect that your stunnel program wasn't up to the task.
You might try and upgrade to the latest stunnel version.
Google search for "stunnel gmail" brought up this page
which might be helpful.
