How to Implement Sender Restricted Groups on Qmail-LDAP environment

Contents[edit]

Sender Restricted Groups When a Sender send a mail to the group , the Qmail see whether the sender is allowed to send the mail or not . Also Sends back a mail to the sender , for him to reply and release the mail to the group members .

We add a users on mail group who can receive a mail when ever a sender send a mail on this group.

Please have following example of Sender Restricted group implemented in LDAP

# everyone@sceh.net, everyone, sceh.net  
dn: uid=everyone,ou=sceh.net,dc=sceh,dc=net
objectClass: top
objectClass: inetOrgPerson
objectClass: qmailUser
objectClass: phpQLAdminBranch
accountStatus: active
uid: everyone
mailHost: mail.sceh.net
cn: everyone
mail: everyone@sceh.net
mailMessageStore: sceh.net/everyone
userPassword:: e0NSWVBUfUdQOXRXOFJxTUo3Tm8=
deliveryMode: forward
mail: everyone@sceh.net
mailAlternateAddress: everyone-catchall@sceh.net
mailMessageStore: sceh.net/everyone
sn: everyone
mailForwardingAddress: rahul@sceh.net
mailForwardingAddress: abhilekh@sceh.net

mailForwardingAddress: macharya@sceh.net
mailForwardingAddress: manisha@sceh.net
mailForwardingAddress: michael.choudhary@sceh.net

Please note

• objectClass: qmailGroup is mandatory.
• The Restricted Sender is defined a email address by rfc822sender . The sender can belong to any domain . You can also define dnsender
• To Ensure that the mails generated by the sender are authentic in nature , senderconfirm: TRUE is specified . An return mail to the same ID will be generated by Qmail ( Qmail-secetary ) and the sender has to reply this mail to release the sent mail to Group .
