If I define the company1.com in the my destination and have company2.com in the parameter virtual_mailbox_domains then mail for company1.com gets delivered properly but those for company2.com gets rejected. I get the following type of message in the maillog Jan 20 15:17:39 mail postfix/virtual[1692]: 6E16F17E20: to=<a...@company2.com>, relay=virtual, delay=0, status=bounced (unknown user: "a...@company2.com") I tried to increase the verbosity of virtual daemon at master.cf. But could not make much from the result. I am giving below the log output with the increased verbosity: Jan 20 15:38:59 mail postfix/virtual[2191]: dict_ldap_lookup: No existing connection for LDAP source accounts, reopening Jan 20 15:38:59 mail postfix/virtual[2191]: dict_ldap_connect: Connecting to server ldap://127.0.0.1:389 Jan 20 15:38:59 mail postfix/virtual[2191]: dict_ldap_connect: Actual Protocol version used is 2.
