I made the attached patch and built the package successfully with mock.
I admit I'm not much of a C programmer either -- and by "admit" I mean
"trumpet" ;-D -- but the way I figured this out was as follows, in case
it helps you get a leg up.  This will all be trivial to all the folks
around here who program in their sleep, so I apologize for boring them.

1.  The error messages say that gcc doesn't know anything about
MD5_DIGEST_LENGTH, which is probably a constant expected to be declared
in some included .h file somewhere.  I did a grep in the package source,
so I figured it must be in a system-wide include somewhere.  I decided
to start by looking at openssl.

2.  I downloaded the rawhide version of openssl, opened the package with
rpm2cpio and grep'd in the /usr/include stuff, and found it
in /usr/include/openssl/md5.h.

3.  That header is not included anywhere in any of the .c or .h files.
So I added this as an #include in imapcommon.c and generated the patch.
(I don't know if this is the best place for it, but it at least seemed
non-ugly.)

After changing the .spec file, mock built it OK!
