PostgreSQL is an SQL database engine. VPOP3 and PostgreSQL In VPOP3 2.x, VPOP3 uses a database engine called SQLite for its database needs. SQLite has limited locking facilities, so on busy systems we encountered problems where databases would need very frequent updates, and the lock limitations would cause the updates to take a long time. For this reason we added optional support for PostgreSQL to later versions of VPOP3 2.x. text/html 2018-11-14T10:45:49+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.pscs.co.uk/faq:which_ports_does_vpop3_use?rev=1542192349&do=diff Which Ports does VPOP3 use?

With IMAP4 your mail is stored and manipulated on the mail server. So, if you move a message from one folder to the other, the message is moved on the server. If you send a message, your mail client will (usually) put a copy into your 'Sent Items' folder. If you delete a message, it is deleted from the server, and so on. text/html 2018-11-14T10:45:49+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.pscs.co.uk/faq:pop3?rev=1542192349&do=diff POP3 Protocol POP3 is the most basic email protocol for collecting mail which is in common use. Almost all email client programs (such as Microsoft Outlook & Outlook Express, Mozilla Thunderbird, etc) can collect mail using POP3. With POP3, mail is usually downloaded by the email client and stored on the user's local PC. It is then deleted from the mail server, so the only copy is on the user's PC. Any mail folders etc are all managed on the user's PC. text/html 2018-11-14T10:45:49+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.pscs.co.uk/faq:what_is_webmail?rev=1542192349&do=diff What is Webmail? “Webmail” is a term used to describe an email client which is accessed through a web page rather than as a standalone program.
