All Rspamd users who are using
rspamd.com fuzzy storage might see the following messages in the log:
fuzzy_check_timer_callback: got IO timeout with server rspamd.com(188.8.131.52), after 3 retransmits
Normally, Rspamd re-resolves hostnames in this case. However, if there is a single server specified (as enabled by default) there is no resolving on errors. Unfortunately, this bug has been fixed merely in the master branch and is not released in the stable versions yet.
The quality of filtering might be temporary reduced as fuzzy storage helps to filter certain spam types.
You just need to restart Rspamd and it will use the new IP address as intended. We do apologise for any inconveniences caused.
