Possible to set quota in size and number of messages

[J Doe]

Hello,

I am using Dovecot 2.2.33.2 and am attempting to set quotas on mailboxes.

I currently have the following:

        plugin {
                quota = dict:User quota::file:%h/dovecot-quota

                quota_rule = *:storage=10G

                quota_rule1 = INBOX/Inbox:storage=+30M
                quota_rule2 = INBOX/Trash:storage=+30M
                quota_rule3 = INBOX/Deleted Messages:storage=+30M
        }

If I check the quota via Apple Mail version 11.5 (3445.9.1) on Mac OS X 10.13.6 
by selecting “Get Account Info” it displays the correct quota size in bytes but 
also states “0 messages” (in that it states I can store 0 messages).

Is there a way to signify to an IMAP client that the quota should be _EITHER_ 
10 GB or 100,000 messages, just so a user doesn’t see that they can store a 
total of 0 messages ?

My initial thought was to alter the previous quota settings by adding:

        quota_rule4 = INBOX:messages=100000

… and restarting Dovecot and Apple Mail, but upon checking the quota’s on the 
user’s account, I still see that a user can store 10 GB or 0 messages.

Thanks,

- J
