Properties of a user.
Properties of a user.
In this screen, you can see the following things.
Primary Mail Address: aghaffar@ispman.net
This is the default email address of the user that corresponds to the username.
This address cannot be changed by the domain admin.
Primary Mailbox Address: aghaffar_ispman_net@cyrus03
This defines the address on the mailbox server.
Scenario 1:
Mail arrives for aghaffar@ispman.net
Mailserver communicates to the LDAP server:
Mailserver: Do you know where is the mailbox for user whose mail address is aghaffar@ispman.net
LDAP Server: Yes. its aghaffar_ispman_net@cyrus03
Mailserver to himself: Am I cyrus03 or is it one of my nicknames?
If yes , deliver mail localy to aghaffar_ispman_net
If no, delivery mail to cyrus03 via SMTP for aghaffar_ispman_net
Then you also see MailForwardings
These are the addresses where the mail should be delivered in addition to the default mailbox.
same scenario like above, but this time the LDAP server return:
aghaffar_ispman_net@cyrus03 and atif_g@yahoo.com
Mailserver delivers to both of them.
Then we have Mail Aliases
These are simply aliases on which the user can recieve mails.
The first and second one is simple. If mail comes for
aghaffar@ispman.net
or
atif@ispman.net
or
atif.ghaffar@ispman.net it gets delived to aghaffar_ispman_net@cyrus03 and atif_g@yahoo.com
The last one is sometimes called catchall alias.
If a mail is not delivered to any one, then it will be delivered to this user.
You can also have a mail alias with the @domain.tld example an alias
admin
now admin@anydomain.tld will come to this mailbox unless it is explicitly defined for someone else.
Example:
Mailserver communicates to the LDAP server:
Mailserver: Do you know anyone acception mails for support@ispman.net?
LDAPserver: Nope
Mailserver: Okay, do you know anyone who will accept mail to support?
LDAPserver: Nope
Mailserver: arrrrgggggh. Do you know anyone who will accept for @ispman.net?
LDAPserver: Yes aghaffar_ispman_net@cyrus03 and atif_g@yahoo.com
Mailserver: bye!
