Hi, tried to Google/etc to see what to tweak.. not finding anything helpful.
So.. I've been running my private mail through a Linux server since approx
year 2000. The OS has been various flavors of Fedora or CentOS, since for
work, I have to spend all day supporting some sort of Red Hat flavor.
So I run SquirrelMail on top of Dovecot and Postfix on CentOS 7, things
have been great for like forever. I recently ran updates and all my INBOX
folders disappeared. I have made no configuration changes in at least 5
years. I can't seem to resolve/figure out what's going on. I have
backups
to see everything before the update. I've noticed that my subscriptions
file is missing all the folders, which are all in this file in the
backups. If I repopulate this file with the names, the next time I access
mail, they are all removed. Most of my mail is in folders, therefore I
have access to almost none of it (can see new stuff coming in, but can't
sort it anywhere).
k, for the details.. I was running dovecot-2.2.10 (2.2.10-8.el7.x86_64)
and was updated to dovecot-2.2.36 (2.2.36-3.el7_7.1.x86_64) with yum
updates.

Makes sense. I'm not a dovecot expert, but in terms of RHEL, have you
checkd that the yum update didn't change file permissions, or enable
selinux or do something like that?

Can you see the mail using none IMAP based tools? What do the dovecot
and postfix logs show? And what about squirrelmail? Check all your
logs for permissions issues.
What else got updated when you did the yum update?
doveadm log errors
might give you some hints.
