I'm not sure if this has been asked before, but the list archives
appear to be down and i can no longer connect to the anonymous imap
server (Thunderbird doesn't have a concept of anonymous login,
without LOGIN, apparently).
Is there a way to prevent the frontend machines in a MURDER cluster
from issuing referrals?
Thanks for your replies.
I was given the attached patch by a sysadmin at PSU, which I am using
here in production. After you apply the patch, simple add the
following to your imapd.conf on your frontends:
# On frontend servers, disable referrals
proxyd_disable_mailbox_referrals: 1
I have not tested this on the v2.3.x series.
