We undertook the first stage of our IMAP server upgrade yesterday and
introduced a front-end proxy running Cyrus 2.2 in front of our sole
back-end server running Cyrus 2.2.
Since the upgrade, when a Pine user sends an email, the email is sent
fine however when Pine appends the message to the sent-mail mailbox it
asks the user to reauthenticate. Looking at the telemetry, the proxy
server is advertising MAILBOX-REFERRALS[1] and Pine is trying to use
them[2] but isn't able to silently reauthenticate the user.
Looking at the man pages for imapd.conf there is a useful feature
proxyd_disable_mailbox_referrals however this was introduced in Cyrus 2.3.
Does anyone have any suggestions as to how to stop the front-end proxy
server from advertising MAILBOX-REFERRALS and/or for Pine to ignore such
capabilities.
Many thanks,
Dave.
