We have a LDAP-integrated Zimbra server where we use a "short form" LDAP account name, as in firstinitiallastname, eg, 'jdoe'. We want to employ email addresses with format firstname.lastname, eg, john.doe@domain.com. No email aliases.

Is there a way to make a 'jdoe' LDAP account employ a 'john.doe@domain.com' email address (with no email alias)...and generalize this approach for all accounts?
