In VPOP3 v3 and later, VPOP3 uses a PostgreSQL Database server for data storage, so if the database server is not running, VPOP3 will not be able to start properly. In this case, the VPOP3.EXE process may appear in Task Manager, but it won't respond to anything, or it may appear in Task Manager and then stop after a short period. text/html 2018-11-14T10:45:49+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.pscs.co.uk/how_to:what_is_the_best_practice_to_delete_old_messages_from_the_vpop3_archive_folder?rev=1542192349&do=diff What is the best practice to delete old messages from the VPOP3 archive folder? You should use the 'Offline' tab in the VPOP3 Message Archive settings to tell VPOP3 to move old messages into a ZIP file. You can then store this ZIP file somewhere safe in case you need to refer to it in the future. (If you know you won't want to ever refer to these old messages, you could just delete the ZIP file, but storage costs nowadays are so cheap, we'd recommend keeping it, just in case). text/html 2018-11-14T10:45:49+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.pscs.co.uk/reference:attachment_extraction_script?rev=1542192349&do=diff Attachment Extraction Scripting This is the 'extraction.lua' script.
