[Dovecot] Duplicates when switching from Qpopper to Dovecot pop3
Hi All, Our test users re-download the mail they've left on the server when they switch from Qpopper to Dovecot. Qpopper includes the X-UIDL header - X-UIDL: X8V"!E)<"!58?"!"9C"! - on read messages. Any suggestions are appreciated. I've included my dovecot configuration.
Thank you, Tristan

Hi All, Problems can sometimes be solved by _carefully_ reading the documentation:
<snip>
Some clients re-download all mails if you change the hostname in the client configuration. Be aware of this when testing.
<snip>We converted without a hitch this morning. Thank you for great software. Tristan
