Bill,
Still working through this problem.. I haven't heard back yet from the support engineer but he works different hours I think (different timezone). Any help moving forward before Monday would be great...I have been debugging this as best I can without success. have checked forum/wiki entries and made sure everything obvious was OK (libraries, binaries etc are all from Zimbra).
I noticed here that the saslauthd_path was comment out (the mux does exist int his path and zimbra perms are correct). I tried uncommenting this and restarting but this made no difference:
/opt/zimbra/cyrus-sasl/lib/sasl2/smtpd.conf
log_level: 3
pwcheck_method: saslauthd
mech_list: PLAIN LOGIN
# saslauthd_path: /opt/zimbra/cyrus-sasl/state/mux
also this file looks good: /opt/zimbra/cyrus-sasl/etc/saslauthd.conf
zimbra_url:
https://mail.mydomain.com/service/soap/
zimbra_cert_file: /opt/zimbra/conf/smtpd.crt
zimbra_cert_check: off
