Hi,
during a migration (cyrus -> dovecot) we ran into trouble¹ using 'doveadm backup' with 2.2.9. So I built 2.2.22 and 2.2.23, but they expose quite different behaviour.
2.2.22 seems to work at least partially, but 2.2.23 complains about a non existing user (root?).
The command I'm running is:
doveadm -o pop3_uidl_format=%v.%u \
-o imapc_master_user=cyrus -o imapc_password=* -o imapc_host=* \
-o mail_fsync=never \
-o imapc_ssl_verify=no -o imapc_ssl=imaps -o imapc_port=993 \
backup -f -u heiko -R imapc:
Using 2.2.9 or 2.2.22 it works, using 2.2.23 "-u …" is ignored and I've to pass the user via the USER environment.
But according to the manpage of doveadm-sync
-u user/mask
Run the command only for the given user. It's also possible to use
'*' and '?' wildcards (e.g. -u *@example.org). When neither the -A
option, nor the -F file option, nor the -u user was specified, the
command will be executed with the environment of the currently
logged in user.
Interestingly enough -u 'heiko*' works fine, even with USER=root. So the environment doesn't seem to override -u … always.
Maybe an important side note: the user 'heiko' doesn't exist as a local system user, he is known via LDAP only.
And for e.g. 'doveadm quota -u heiko' it works as expected, even with 2.2.23.
¹) solved meanwhile by using -o mail_plugins= as the quota plugin seems to crash 'doveadm backup'
