| - | ======Duplicated Messages====== | + | [[https://helpdesk.pscs.co.uk/ |
| - | + | ||
| - | If you get duplicate messages when VPOP3 downloads mail from the ISP there are several common reasons for this: | + | |
| - | + | ||
| - | =====Multiple POP3 mailboxes on the ISP===== | + | |
| - | If your ISP gives you one POP3 mailbox for each VPOP3 user, then you have to tell VPOP3 which user each mailbox is associated with. If you don't do this, then when a message is sent to two VPOP3 users, each user will receive two copies of that message. | + | |
| - | + | ||
| - | To link each ISP mailbox with a VPOP3 user, go to the VPOP3 **Mail Connectors -> Mail Collectors** page. Then, for each Mail Collector you have, in the **POP3 Routing** tab, choose **Send all messages to a specified user/list** and select the VPOP3 user who this POP3 mailbox is for. | + | |
| - | + | ||
| - | =====Download Errors===== | + | |
| - | If VPOP3 gets disconnected when downloading mail from the ISP and you do NOT have Leave Messages on Server for X days enabled on the In Mail tab in VPOP3, then the next time VPOP3 connects it will download all the messages again. | + | |
| - | + | ||
| - | This is because, although VPOP3 has asked the ISP to delete the message from the ISP POP3 mailbox the POP3 standard says that if a connection error occurs, the ISP must automatically undelete all messages which were deleted during that session. | + | |
| - | + | ||
| - | The solution is to tell VPOP3 to Leave Messages On Server for at least one day. | + | |
| - | + | ||
| - | =====Multiple Identical Mail Collectors===== | + | |
| - | Check that you do not have multiple identical Mail Collectors defined in VPOP3. If you do,then remove all but one of them. | + | |
| - | + | ||
| - | =====Multiple Copies of VPOP3 running===== | + | |
| - | Using the **Processes** list in Windows Task Manager, make sure you do not have more than one copy of **VPOP3.EXE** running. (Click on the **Show Processes for all Users** button/box if there is one). | + | |
| - | + | ||
| - | =====Other causes===== | + | |
| - | If none of these common causes matches your problem, then you need to send a copy of a set of duplicated messages (eg if you receive two copies of a message, send both copies) to support@pscs.co.uk | + | |
