New feature in v6.1 – Store and Forward
Posted by Paul Smith on 13 June 2013 08:28 AM
LAN forwarding has been a feature of VPOP3 for many years.
With LAN Forwarding, VPOP3 will forward messages on to another mail server using SMTP. This has two common uses:
Using VPOP3 in either of these situations can improve reliability as mail is still accepted even if the main mail server is down, however, the messages which VPOP3 has queued for forwarding to the main server are not available for viewing, so mail can still not be accessed until the main server is back working.
Store and Forward
In v6.1 we added a new feature to VPOP3 Enterprise called “Store and Forward”. In this case, VPOP3 will both store the mail in a local VPOP3 mailbox, and also forward it to another mail server.
If you use this feature, then users will be able to log into their VPOP3 account to view their mail, just as if this VPOP3 was their normal mail server, but if/when the main mail server comes back online, the mail will be forwarded onto that as with normal LAN forwarding.
However, it’s cleverer than simply copying messages to two places (which could easily be done with older versions of VPOP3):
Configuring Store and Forward
To configure Store and Forward, you first need to create all your users in your VPOP3 server, by going to the Users page, and pressing New or Bulk Add Users to add your users.
Next, edit the user by double-clicking on them, and go to the Advanced tab. You will find two boxes in there called Store and Fwd email target and Store and Fwd target server. In the email target box enter the full email address on the target mail server. In the target server box, enter the address of the target mail server (see notes below).
Finally, remove any previous LAN Forwarding configuration. The usual places this may be set is in Local Mail -> LAN Forwarding -> Configuration or in the Routing tab of the users’ settings (check for entries beginning with SMTP: in the Assistant or Forwarding settings).
When entering the Store and Fwd Target Server address:

Pruning old messages automatically
Posted by Paul Smith on 10 June 2013 01:58 PM
In VPOP3 Enterprise 6.2 and later you can tell VPOP3 to automatically delete old messages, based on specified criteria.
You can either do this globally, for all users, or just for specific users.
To edit the global criteria (rules), go to Settings -> Database -> Message Store, and look at the Global Prune Rules section. To edit the criteria for a specific user, edit the user, and go to the Prune Rules tab.
Both types of rules are configured similarly, so we will just describe the user rules here
How to add/edit a rule
To add or edit a “prune rule”, press the Add Rule button. This will add a new rule to the table, with a set of default settings. Don’t worry, this rule doesn’t take effect until you press the Submit button.
Now, you can simply alter the settings in the columns in the table, by clicking them. The settings define which messages should be deleted, not what should happen to messages.
The folder column defines which folder(s) the prune rule applies to. Initially this is set to Inbox, but you can click on the folder name to set it to any folder name you wish. Alternatively, you can set it to * to match all the folders for this user (note that you cannot use wildcards in conjunction with other characters (eg “Inbox/*” will not work as you expect).
The age column defines how old messages are before they will be deleted. This is set in days, and is based from when VPOP3 first saw the message. It is not based on when the message was written or sent. If the Age is set to 365, then VPOP3 will automatically delete any messages which were received by VPOP3 over 365 days ago.
The size column defines how big messages should be before they are deleted. This can be useful to only delete big messages, or to delete big messages sooner than smaller messages. The default is for no minimum size (all sized messages), but you can set it by clicking in that column.
The read column indicates whether this rule will apply to read messages, unread messages or either. This could be useful if you only want to delete messages that have been marked as read.
The flagged column indicates whether this rule will apply to flagged (starred) messages, unflagged messages, or either. This could be useful if you want users to be able to ‘star’ important messages so they don’t get deleted automatically.
If the deleted column is checked, then VPOP3 will only apply this rule to messages which have the IMAP4 ‘Deleted’ flag set. If this column is not checked, then the rule will apply to all messages. This can be useful if your users do not purge (or ‘expunge’) folders regularly
If the spam column is checked, then VPOP3 will apply this rule to messages marked as spam by VPOP3. This can be useful if you are not using the VPOP3 quarantine facility, but are, instead, having VPOP3 deliver the messages to the user, and are using VPOP3 Message Rules or email client rules to put spam messages into an IMAP4 folder.
