We have a Dovecot server configured for internal usage purpose and Thunderbird as a email client with IMAP
protocol. I have never used either of the software, so my questions are a bit naive.
Due to some reasons we downloaded all emails to local Thunderbird uisng POP3
few days back, now we are using IMAP
and POP3
(as backup purpose). Today first all messages are downloaded using POP3
but in IMAP
, messages after 20th JAN are only getting. I thought it is due to option having checked Leave messages on Server
in POP3 settings. I'm confused that whether message before 20th JAN are remains on server or deleted, how to know this ?
Is the POP3
server settings.
