  • Duplicated Messages after migration from google workspace

Hi,
I have Emails in Google workspace
I am trying to migrate them to my server using the mail cow sync job, but when I tried to migrate them the space was greater than the actual space in Google workspace and some messages are duplicated.
EX. one of them was 8GB after migration it became 21GB.

Do you have a solution for that issue, please?
thanks.

See here:

Especially this option and explanation:
--skipcrossduplicates is optional but it can save Gigabytes of hard
disk memory. Within imap protocol, Gmail presents Gmail labels as
folders, so a message labelled "Work" "ProjectX" "Urgent" ends up in
three different imap folders "Work" "ProjectX" and "Urgent" after an
imap sync. Option --skipcrossduplicates prevent this behavior.

Have something to say?
