You mean: You have a local directory A, and remote directories B and C, and want to copy those files in A to be copied to C, which are different from B? Sorry to misunderstand you.
In this case you indeed need to rule out your own algorithm, but unless I overlook something, you haven't answered yet my earlier question, how you exactly define "difference". Content? Last modification time?
You still can use rsync for getting the difference. Please look at the
--dry-run switch of rsync. The idea is to first do a dry run of rsync of A vs. B, collect from it the names of the files which would be copied, and then use this list to actually copy the files to B, using for instance scp or rcp.

rmf(1) General Commands Manual rmf(1)
NAME
rmf - remove folder (only available within the message handling system, mh)
SYNOPSIS
rmf [+folder] [-help] [-[no]interactive]
OPTIONS
Prints a list of the valid options to this command. Asks for confirmation before deleting a folder. By default, rmf deletes a folder and
its messages without asking for confirmation. If you specify the -interactive option, rmf asks if you are sure before deleting the folder.
You are advised to use this option, since when rmf deletes a folder its contents are lost irretrievably.
DESCRIPTION
The rmf command removes all of the messages within the current folder, and then removes the folder itself. If there are any files within
the folder which are not part of MH, they are not removed, and an error message is displayed.
You can specify a folder other than the current folder by using the +folder argument. If you do not specify a folder, and rmf cannot find
the current folder,rmf asks you whether you want to delete +inbox instead.
If the current folder is removed, it makes +inbox current.
Note that the rmf command irreversibly deletes messages that do not have other links, so use it with caution.
If the folder being removed is a sub-folder, the parent folder becomes the new current folder, and rmf tells you that this has happened.
This provides an easy mechanism for selecting a set of messages, operating on the list, then removing the list and returning to the current
folder from which the list was extracted.
Using rmf to delete a read-only folder deletes the private sequence and current message information from the file, without affecting the
folder itself. If you have sub-folders within a folder, you must delete all the sub-folders before you can delete the folder itself.
PROFILE COMPONENTS
Path: To determine the user's Mail directory
EXAMPLES
This example shows how rmf asks for confirmation when the -interactive option is used: % rmf -interactive +test Remove folder "test"? y
FILES
The user profile.
