How To Allow Mail Relay Through VPOP3

Anonymous (anonymous@undisclosed.example.com) — 2025-05-21T07:57:18+00:00

How To Allow Mail Relay Through VPOP3 If you are allowing remote access into VPOP3 to collect mail then you may also want those remote users to be able to send their outgoing mail through VPOP3 as well. This is more complex than allowing users to collect mail, because, by default, SMTP connections are not authenticated. This means that when someone tries to send a message through VPOP3, VPOP3 doesn't know who that user is. This can cause a problem if unauthorised users try to send mail through…

Error 1348 - The validation information class requested was invalid We have had a report of this error when VPOP3 is trying to access a file share, eg for storing backups or archived messages. In the case where it was reported, it turned out that a Windows Update had converted a 'local' user account into a 'Microsoft' account and that was preventing VPOP3 from accessing the file share, because VPOP3 was trying to use a local account.

Out of Disk Space When Sending Mail

Anonymous (anonymous@undisclosed.example.com) — 2018-11-14T10:45:49+00:00

Out of Disk Space When Sending Mail The first thing you should do is check that there is enough free disk space on the disk where VPOP3 is installed. VPOP3 requires a certain amount of free space before it will allow new messages to be sent, so the disk might not be totally full, but VPOP3 will still report that there is insufficient disk space when you try to send a new message. This buffer zone is designed to help prevent the disk totally filling up, which can cause lots of bigger problems!
