Hi
I am starting to see a lot of these errors on a user:

imap(xxx@example.com)<117976><1kR5ozIDwFxXNjqC>: Error: Mailbox INBOX: UID=1726: read() failed: Cached message size larger than expected (7720 > 4096, box=INBOX, UID=1726) (FETCH BODY[])

Any good ideas as to how to fix this?

  • It would seem that if I delete the corresponding dovecot.* files in “mailcowdockerized_vmail-index-vol-1” “.INBOX” the problem went away.

    Time will tell if this was a one off issue.

Have something to say?
