--userregextrans :-)

[Peer Heinlein <p dot heinlein at heinlein-support dot de>]

Very often it's necessary to change usernames during the migration from 
one server to another.

Sure, it's easy to write a little script to use different usernames on 
host1 and host2.

But consequently it would be necessary to migratione usernamens in ACL-
rules too. Otherweise the whole ACL-setup is broken.

That's nothing we can do with just some parameters, because each 
imapsync migration process has to know *all* pairs of old/new usernames. 
-A single account will have several ACL-rules for different users.

Migrating ACLs would be easy if imapsync would understand a parameter 
like --user-translation-file:

olduser1 newuser1
olduser2 newuser2
olduser3 newuser3

And sometimes it's possible to describe all changes by a simple regular 
expressions. A parameter like "--userregextrans" would be nice to (for 
stuff like s/(.+)@(.+)/\2_\1/).

imapsync should migrate all usernames during the --syncacl-process.

Having that kind of translation-file the parameter "--user2" could be 
optional:

If no "--user2" is given, then "--user1" is used (same for --
password2/--password1).

If furthermore --user-translation-file or --userregextrans exists, then 
imapsync should migrate the username used for the login (and for ACLs) 
automatically from old to new.
