merge two accounts ... maybe with imapsync

[Alexander Schröter]

Hello I have to solutions to my problem in my head maybe someone knows a 3rd 
or how to make one of the two happen.

Is there a way to sync 2 imap accounts with each other. I would say like a 
merge.

Why? Because I want my mails to remain at my ISP ... there I have backup and 
compared to my kolab-server a way better uptime.

To use the full advantages of my kolab server I thought it would be nice to 
have all the mails on the kolab server too.

#1
I now use imapsync to sync my ISPimap to my Kolabimap. Problem is that this 
setup only works in a Source-Target direction where I would like a merge 
aproach. To rearrange mails on the kolab server and have them that way on the 
ISPserver too.

I hope this makes somewhat sense to someone.
Maybe you guys have an idea how accomplish this.

#2
I also have another Idea to solve my problem. Would it be possible to not use 
a local mailbox on the kolab server but to connect to a remote one (myISP). So 
that everything (maybe just the mails and not the contacts, dates, tasks etc.) 
I do is synced with my ISPs Server.

This would as far as I understand fix all the sync problems.

Thank you very much.
I really enjoy the functionality of kolab :)
