Ezsra,
Have you read and followed all of the steps outlined in the Upgrade documentation for 3.0?  You can find them here:
https://www.cyrusimap.org/3.0/imap/download/upgrade.html
[Note: use that link, since the current stable version is 3.2, and simply navigating the website will lead you to the newer version, not the 3.0 which you're using.]

If you haven't done these steps, as described, you may need to start over.  Pay special attention to steps 5 & 6, and follow the links within for additional information on settings which have changed, like 'unixhierarchysep:' and 'altnamespace:'.

Cheers,

Hi Nic!

Here is some of the information you mentioned.

We use the RPM packages from the yum repositories.

Old Server:
OS: Oracle Linux 6.10
Postfix: postfix-2.6.6-8
Cyrus: cyrus-imapd-2.3.16-15

New Server:
OS: Centos 8.2.2004
Postfix: postfix-3.3.1-12
Cyrus: cyrus-imapd-3.0.7-16

Permissions on the inbox:
I did not have the "anyone p" ACL. I added that. I also add the "a" to the testuser ACL. Neither of these helped. I also gave Cyrus the "All" ACLs on the inbox. This made no difference.
localhost> lam user.testuser
cyrus lrswipkxtecda
testuser lrswipkxtecda
anyone p

We do not use the autocreate feature. We create the accounts using an inhouse tool.

Ezsra,
You haven't told us which versions of Cyrus you both were using, on the old server, and are now using, on the new server.  A lot of things have changed between v2.X and 3.X, including many "default" settings.  Also, whose builds of Cyrus are you using?  Did you build your own, or did they come from repositories, or what?  Again, this matters both for the old and new versions.

Lastly, what are the permissions on the mailbox involved?  As the admin user, use the "lam user/<username>" command in 'cyradm' to check this.  The user's 'inbox', 'user/<username>' should have permissions like this:
localhost> lam user/testuser
anyone p
testuser lrswipcda
That "anyone p" is necessary for Posting permissions, allowing program delivery to the mailbox.

And out of curiosity, does the mailbox actually exist?  By default, newer Cyrus IMAPd do not autocreate mailboxes, or at least doesn't do so in the same way it used to.  You mention EL6 and CentOS.  Older Redhat-ish Cyrus packages included their own autocreate, which I believe was enabled by default.  Now, in 3.X, there's a new mechanism, and by default it's not enabled.  Your configurations do not show any autocreate settings.

Check the man page for imapd.conf(5) for details on this.  In particular, search for this:
	autocreate_post: 0
              If enabled, when lmtpd(8) receives an incoming mail for an INBOX that does not exist, then the INBOX is
              automatically created by lmtpd(8) and delivery of the message continues.
Also look into the 'autocreate_inbox_folders' setting, which may hold a list of folders, such as Drafts, Sent, Trash, etc. to create along with Inbox.

Notes:
I did notice a difference in the LMTP response from our current production system. The current production system includes the following in the response:

<-  250-STARTTLS

I do not see that on the new system (Response shown above) with the same configuration. Curious why or if that has anything to do with it. I am using a self-signed cert on the new system for testing purposes. Is that why? Do I need to tell LMTP to accept the cert somehow?

Thanks

Sebastian,
Thank you for the response.

I have never heard of this tool but it looks interesting. I will give it a try.

Will let you all know if I find anything.

My favorite tool for mail delivery testing is swaks. You can test LMTP
this way:

swaks --to YOUR-TEST-USER --socket /var/lib/imap/socket/lmtp --protocol LMTP
