Is there a good reference site that lists correct MIME types for various

or is there a general rule to follow for non-standard file types?

There is the x- prefix which is added to proprietary/custom MIME types, but you you should generally try to find one which is documented either with IANA or by the vendor of the file type, instead of making up your own.

Specifically I'd like to know what MIME type should be used for SPSS
portable (.por) files

If you can't find an official one in IANA or find one documented by the software vendor, then you should use application/octet-stream for generic binary files.
