Dear Expert,

I have problem with Zimbra sending mail, at the zimbra log it write :
sep 24 17:..:.. mail2 postfix/smtp[295xx] 95BE....... to=<somebody@mydomain.com>, relay=none, delay=2, status=bounced (mail for mydomain.com loops back to myself)
sep 24 17:..:.. mail2 slapd[59xx] <=bdb_equality_candidates: (ZimbraMailStatus) index_param failed (18)
sep 24 17:..:.. mail2 slapd[59xx] <=bdb_equality_candidates: (ZimbraDomainType) index_param failed (18)
sep 24 17:..:.. mail2 slapd[59xx] <=bdb_equality_candidates: (ZimbraMailStatus) index_param failed (18).....

after that my queued mail has been deleted

for your known this zimbra mail server which has domain mail2.mydomain.com to backup mail.mydomain.com at different server
this mail2.mydomain.com running as guest at vmware server
my NS record ready like this:
mydomain.com 86400 IN MX 10 mail.mydomain.com
mydomain.com 86400 IN MX 10 mail2.mydomain.com

mail.mydomain.com 86400 IN A xxx.xxx.xxx.172
mail2.mydomain.com 86400 IN A xxx.xxx.xxx.165
