I am transitioning between servers (both debian 11.6 with dovecot 2.3.13) and I'm seeing some strange behaviour after the transition: it seems like dovecot is listing the correct subject for the test messages I'm sending in what's shown in my MUA's summary.

But the body of the message is an old message.

Dovecot is serving messages from Maildir folders in the users' home directories.

And I may have messed up some things here: I rsynced the maildirs and then still got some deliveries both places when the MX records were in transition, so I did a belated rsync, thinking that "Maildir can handle that".

But I weren't thinking about the dovecot files, ie: drwx------ 2 sb sb 155648 Feb 11 06:43 cur -rw------- 1 sb sb 30 Nov 23 18:14 dovecot-keywords -rw------- 1 sb sb 116407 Feb 11 06:43 dovecot-uidlist -rw------- 1 sb sb 8 Feb 28 2022 dovecot-uidvalidity -rw------- 1 sb sb 0 Mar 17 2011 dovecot-uidvalidity.4d821095 -rw------- 1 sb sb 38016 Jan 31 15:38 dovecot.index -rw------- 1 sb sb 203852 Feb 5 21:37 dovecot.index.cache -rw------- 1 sb sb 15076 Feb 11 06:43 dovecot.index.log -rw------- 1 sb sb 6424 Feb 4 08:06 dovecot.list.index -rw------- 1 sb sb 7796 Feb 11 06:43 dovecot.list.index.log -rw------- 1 sb sb 3048 Mar 6 2022 dovecot.mailbox.log drwx------ 2 sb sb 4096 Feb 11 06:43 new -rw------- 1 sb sb 738 Mar 6 2022 subscriptions drwx------ 2 sb sb 4096 Feb 6 22:05 tmp

Are there any of these that could have been adversely affected by the rsync?

Will regenerating these files fix the behaviour where I get the wrong article when fetching them?

What is the best way to regenerate them?

Can these feil be safely deleted and will be autogenerated?

(I also see that some of these files are quite old. I had another server transition in 2017, so the files from 2011 has been rsynced into that server and not touched since)

Thanks!
