Because of this, it has inherited some code that makes sense for isync, but not for imap-send. In particular, when storing a message, it does one of: - if the server supports it, note the server-assigned unique identifier (UID) given to each message - otherwise, assigned a random UID and store it in the message header as X-TUID Presumably this is used in isync to be able to synchronize mailstores multiple times without duplication. But for imap-send, it the values are useless; we never do anything with them and simply forget them at the end of the program. This patch removes the useless code. Not only is it nice for maintainability to get rid of dead code, but the removed code relied on the existence of /dev/urandom, which made it a portability problem for non-Unix platforms.
