Detail
Sometimes it is useful to set WorkgroupMail to download messages from the POP3 server in more manageable blocks. This could be the case if you have many messages in your mailbox at the ISP. If the connection should fail for any reason then any messages already downloaded will be downoaded again and again until all are downloaded in one attempt. The chances of the download failing will increase with the number of messages in the mailbox.
To configure WorkgroupMail to download in blocks, you must add a registry entry to the computer running the WorkgroupMail server. The registry entry is:
HKEY_LOCAL_MACHINESOFTWARESoftalkWorkgroupMailAdvanced downloadBlocks
At the Run command on the Start menu type Regedit and click OK. Browse to HKEY_LOCAL_MACHINESOFTWARESoftalkWorkgroupMail. If no Advanced key exists, create one by right clicking on the Softalk registry key. Select Advanced and right click to create a new DWORD value called downloadBlocks. Double click this and set the value to be the number (in decimal) of messages WorkgroupMail should download at any one time.
If you have a corrupt message at the ISP that is causing messages to be downloaded repeatedly then this value could be reduced in stages to one until all messages before the corrupt message have been received. The corrupt message can then be deleted (see related FAQ).
