Account & Mail Pruning

These options are used to designate when or if inactive accounts or old messages will be deleted by MDaemon. Each day at midnight MDaemon will remove all messages and accounts that have exceeded the time limits stated. There are similar options on the Account Editor's Quotas screen that can be used to override these settings for individual accounts.

| See AccountPrune.txt in the "…MDaemon\App\" folder for more information and command line options.

Delete account if inactive for this many days (0 = never)

Specify the number of days that you wish to allow an account belonging to this domain to be inactive before it will be deleted. A value of "0" in this control means that accounts will never be deleted due to inactivity.

Delete messages older than this many days (0 = never)

A value specified in this control is the number of days that any given message may reside in a user's mailbox before it will be deleted by MDaemon automatically. A value of "0" means that messages will never be deleted due to their age. Note: This option's setting does not apply to messages contained in IMAP folders unless you also enable the "PURGE old messages from IMAP folders as well" option below.

PURGE deleted IMAP msgs older than this many days (0 = never)

Use this control to specify the number days that you wish to allow IMAP messages that are flagged for deletion to remain in your users' folders. Messages flagged for deletion longer than this number of days will be purged from their mailboxes. A value of "0" means that messages flagged for deletion will never be purged due to their age.

PURGE old messages from IMAP folders as well

Click this checkbox if you want the "Delete messages older than this many days" option above to apply to messages in IMAP folders as well. When this control is disabled, regular messages contained in IMAP folders will not be deleted due to their age.

Domain Settings

Max message size from authenticated senders [xx] KB (0=no limit)

Use this option if you wish to set a limit on the size of messages that an authenticated sender can send to the domain. The value is in Kilobytes and set to "0" by default, which means no limit. If you wish to set a message size limit for non-authenticated senders, use the "...all other senders" option below.

Max message size from all other senders [xx] KB (0=no limit)

Use this option if you wish to set a limit on the size of messages that a non-authenticated sender can send to the domain. The value is in Kilobytes and set to "0" by default, which means no limit. If you wish to set a message size limit for authenticated senders, use the previous option.

Max account disk space quota [xx] MB (0=no limit) (Cloud only)

Max messages sent per hour [xx] (0=no limit) (Cloud only)

Use this option if you wish to designate a maximum number of messages that the domain can send per hour. Once this limit is reached, further messages are left in the queue until the count resets.
