NON-ASCII symbols in Auto-Reply in one or several mailboxes. This is Plesk bug with ID #PPPM-4946 , that will be fixed in future Plesk updates.

Until fix available, proceed with the following:

Workaround via Plesk

Connect to the server via SSH.
Locate all mailboxes with auto-reply feature enabled:

# plesk db "select m.mail_name, d.name AS domain from domains d, mail m where m.dom_id = d.id and m.autoresponder='true'"
+-----------+----------+
| john | example.com |
| jane | example.net |
+-----------+----------+

Note: In this output, emails with enabled auto-reply option are john@example.com and jane@example.net
Log in to Plesk.
Temporary disable Auto-Reply for the found mailboxes via Domains > example.com > Email address > john@example.com > Auto-reply.
Run plesk repair mail again:

# plesk repair mail
Turn back on Auto-Reply for mailboxes if needed in Domains > example.com > Email address > john@example.com.

Automated solution with a script

Connect to the server via SSH.
Download the attached script:

# wget https://support.plesk.com/hc/en-us/article_attachments/360017476440/fix_plesk_repair_mail.sh
Give the execution permission:

# chmod +x fix_plesk_repair_mail.sh
Run the script:

# ./fix_plesk_repair_mail.sh

Note: This script produces a log file repair-YYYYMMDD-hhmm.log in /var/log/plesk/ with the result of commands.
