FWIW, Zimbra have reinforced to Partners that Zimbra 9 is End of General Support on 31 March 2024. There is an Extended Support period for Zimbra 9 which ends as you say on 31 December 2024. From April through September, Zimbra 9 will receive (it has been explained to us) only “critical” bug and sec...

ldap_bind_url has been empty on every system I’ve touched for a number of years, and I also have a recollection that Support told me it is no longer used.

Sounds like you’ve found a residual use there!

If you are saying there are entries in localconfig on the old server that don’t exist on the new server, please post them here.

Thank you Mark for pointing out the reason. I also see from the daily report we have around 3k-4k SASL LOGIN authentication failure warnings. Will Fail2Ban work for this too? What do you suggest for this? I would appreciate if you please share any wiki/how-to links to depoly Fail2Ban for Zimbra 8.8...
