Re: IMAP locking, LDAP TLS/OpenDKIM issues after 8.7 to 8.8 upgrade

I didn't have PROXY for IMAP and POP3 enabled, neither, nor NIO. Cause I tend to be an early adopter, every time there is a new ZMC version I rush to install it. And at one of the updates the NGINx PROXY and Memcached were mandatory. I enabled the proxy just for webmail not for IMAP, cause I didn't ...

Re: IMAP locking, LDAP TLS/OpenDKIM issues after 8.7 to 8.8 upgrade

Are You using NGINX proxy for IMAP? Is NIO for IMAP enabled? What is the output of this command: zmprov getConfig zimbraImapMaxRequestSize ?

Re: Upgrade and New Install 8.8.5 Web Stops Responding

As written in the upgrade notes of zimbra the new IMAPD is BETA, e.g. It'll not be enabled after install. Never the less I chose the option not to install it at all. My server is a Supermicro one with 4 AMD processors with 12 threads each. Samsung EVO pro SSD and 64GB RAM, had no such issues on 8.7....
