Hello,

we are using doveadm sync to export mdbox to maildir format, so we can use an external tool to convert into an pst file. Since we have enabled zlib compression doveadm sync always exports the maildir gzip compressed.

Are there any ways to prevent the doveadm sync to export the maildir compressed ?

Have tried this: doveadm -o "maildir_copy_with_hardlinks=no" sync -u imap@test.de maildir:~/Maildir

From Wiki: If you want to use dsync to convert to a compressed Maildir you may need -o maildir_copy_with_hardlinks=no (this is set to yes by default and will prevent compression).

Regards, Daniel
