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:
