No, but they have to be stored base64-encoded, not hex-encoded as you have.
It's fairly straightforward to convert one to the other (assuming your
md5 value is a plain unsalted hash of the original password)
e.g. using ruby:
irb(main):001:0>
[["177b8fafcf4d5454f605c563e212f156"].pack("H*")].pack("m").strip
=> "F3uPr89NVFT2BcVj4hLxVg=="
That is, try "{md5}F3uPr89NVFT2BcVj4hLxVg==" in the database.
You might be able to knock up something in mysql which does the conversion
dynamically, e.g. with a user-defined function.
Alternatively, you could look at modifying courier-authlib to accept both
hex and base64 passwords, based on the length seen (24 or 32 characters).
This is what exim does.
