I've done a test upgrade of a cloned server from Courier to Dovecot. So
far, it's working well with most email clients, but when I reconfigure
MailMate to connect to the new server, it gives me this error
The so-called UIDVALIDITY value of the mailbox “INBOX” has
changed. MailMate has to resynchronize the mailbox, that is, purge the
local cache and refetch the messages of the mailbox.
I'm pretty sure I ran the
I'm connecting via IMAP, so I don't think the `pop3_uidl_format` config
option comes into play here. Anyways, the [Dovecot migration
guide](https://wiki1.dovecot.org/Migration/Courier) says: *“With the
v1.1+ migration script you can use any pop3_uidl_format, because the
UIDLs are stored directly in the dovecot-uidlist file.”*.
I just let MailMate resynchronize my test mailbox, and it worked fine
after that (it only asked me to do it once). However, I would like to
prevent any of our users having to resynchronize mailboxes, if possible.
