Issue Mailbox content scrambled after migration from cPanel

[defcon8]

Server operating system version

Debian 12

Plesk version and microupdate number

Plesk Obsidian v18.0.58_build1800240123.15 os_Debian 12.0

Hello,

I'm currently in the process of migrating an account from cPanel to Plesk. The migration system has successfully created all the mailboxes with credentials on the Plesk server. However, upon logging into one of the mailboxes, I've noticed issues with the content:

• While some / very few emails show up correctly.
• Some emails are appearing empty (lacking sender, subject, and content).
• Certain emails display random body content, resembling binary data.
• Despite an inbox badge indicating 20 new emails, only 2 empty ones are visible.

Any insights into what might be causing these issues would be greatly appreciated.

I also noticed that most of the folders of the inbox just list one "empty" e-mail, when I click that, it triggers a warning in /var/log/plesk-roundcube;

[13-Feb-2024 16:38:17 UTC] PHP Warning: Attempt to read property "charset" on bool in /usr/share/psa-roundcube/program/lib/Roundcube/rcube_storage.php on line 466

Do you see the same "wrong" formatted emails and structure when opening emails through an external email client, e.g. Thunderbird?

I tried IMAP using Thunderbird, messages in some folders are being listed. But when you open them the body stays blank. I tried Apple Mail and turn on debugging logging. I think there is a server-side problem;

In /var/log/maillog I see;

Feb 13 20:11:25 srv002 dovecot[840]: service=imap, [email protected], ip=[x.x.x.x]. Error: Mailbox INBOX: UID=3478: read(/var/qmail/mailnames/xxxxxxxxx.nl/xxxxxx/Maildir/cur/1680784388.M317771P20149.srv001.xxxxxxx.nl,S=18105,W=18418:2,FS) failed: Cached message size larger than expected (18105 > 7044, box=INBOX, UID=3478)

Private data manually obfuscated with "x" character in the text above.

Here some views on the message file. In the folder itself I see a mixture of files containing human readable data (mail message format).. and ones that contain binary garbage.
