dsync issues due to Prefix difference?

[Mark Little]

Hi Timo,

Thank you very much for the information.  I had seen the DSync page but 
I was confused as to how to configure it.  I'd definitely love to be 
able to get the proper dsync migration working as I have some clients 
who use POP3 and others who use IMAP and I want to make this seamless 
for all if possible.

Could you please elaborate on how I specify the alternate dovecot.conf?  
I've gone through the man pages and I don't see anything referencing -c 
for doveadm?  Or do you mean that I should be running the full dovecot 
server process from the source server with an alternate configuration?  
If I change the name space won't it fail to find the local folders in 
their mailbox?


Cheers,
Mark
