Messenger Plus! POP3 Gmail Limitations
Everyone’s probably thinking that there is a problem with Plus’s new SSL pop3 feature and Gmail, which Patchou previously stated would be compatible with MsgPlus! 3.50+. However be aware that it is not a bug or problem with Plus! at all, in fact it's how Gmail itself handles the pop3 protocol.
Plus! connects to Gmail using the pop3 protocol and requests the total amount of new messages in your account – which due to the new SSL (Secure Socket Layer) is now possible. However due to the way Gmail stores emails (using labels instead of folders and “threading” sent & received messages together), it will not return the correct number of
new emails when Plus! checks for it. Gmail will instead return the total number of emails received, including ones read, and also emails that you have sent. Over time this will compound with Plus! constantly reporting a higher and higher number of 'new' emails. So, you'll know when you'll get new emails, you'll just don't know how many.
Changing your pop3 settings in Gmail (For example: to “Archive when read”) will only fix the problem partially due to the fact that Plus! sticks to the pop3 protocol and only requests the number of new emails from Gmail, it does
not read nor delete the emails.
Seeing as this is not an error in Plus's SSL pop3 feature this will not be corrected directly in Messenger Plus!. Sorry for this inconvenience
. Let us hope Google will fix their pop3 feature in the near future and abide by the standards of the pop3 protocol.
Thank you and we all hope you enjoy Messenger Plus!
