Hello all,

I have just realized, that my quota config actually works when using the
"ignore" directive, but I am unable to set a separate quota (for example
10G) for the Archives. namespace.

I have tried with:

quota_rule2 = ns=Archives.:storage=10G

but this raises an error message in the logfile:

Jan  9 11:30:01 mail01 dovecot: imap: Debug: Added userdb setting:
plugin/quota_rule=*:storage=3G
Jan  9 11:30:01 mail01 dovecot: imap: Debug: Effective uid=150, gid=8,

Jan  9 11:30:01 mail01 dovecot: imap: Warning: quota root User quota
rule ns=Archives.:storage=10G: obsolete configuration for rule
'storage=10G' should be changed to 'storage=+10G'
Jan  9 11:30:01 mail01 dovecot: imap: Debug: Quota rule: root=User quota

Jan  9 11:30:01 mail01 dovecot: imap: Debug: Quota root: name=Archive
quota backend=maildir args=ns=Archives.


If I add the '+' the error message will not come up again, but when
checkinig the quota value for the folders under the Archives. namespace
I still get the quota size for the Inbox namespace.

Thank you for your kind help

best regards
