Hello Everyone,

My zimbra is running in vsphere esxi 5.5 along with other servers and I had a server crash a few days ago due to a problem in vsphere.

After restart, smtp authentication from clients like thunderbird does not work anymore ! This is the entry in zimbra.log

Apr 2 10:48:39 mailserver postfix/submission/smtpd[23001]: warning: SASL authentication failure: cannot connect to saslauthd server: Connection refused
Apr 2 10:48:39 mailserver postfix/submission/smtpd[23001]: warning: SASL authentication failure: Password verification failed

Apr 2 10:48:39 mailserver postfix/submission/smtpd[23001]: warning: unknown[192.168.2.111]: SASL LOGIN authentication failed: generic failure

zmcontrol status shows all services running. I cannot find any saslauthd running.

Can anyone help me troubleshoot this problem please ?

Thanks in advance.

Ram

Can you try like root user

/opt/zimbra/libexec/zmfixperms -extended

And then like Zimbra user

zmcontrol restart

And let us know?
