Hi all,

I am running sendmail with MailScanner on CentOS. I want to enable some restrictions.

Restrictions are given below.

All clients Currently can send Bcc from their workstations as usual. I want to disable (block Bcc) that feature. Can I do it from the Sendmail Server ?

No...or it will take some serious ruleset creation. Better install libmilter (sendmail-devel package) and use mimedefang.


All clients currently can send Cc form their workstations as usual. I want to limit it. Let's say about 5 Cc s .

Same as above if not more difficult to achieve with sendmail rulesets.


All incoming mails are forwarded to another email address by using an alias .

pls see below for ,

/etc/aliases

john:     john, mailbackup@xxxxxxxxxxx <mailto:mailbackup@xxxxxxxxxxx>
userx:   userx,mailbackup@xxxxxxxxxxx <mailto:mailbackup@xxxxxxxxxxx>

The above for incoming mail.

Better use .forward rules.


Can I make a copy of ALL OUTGOING mail to one email address? let's say mailoutgoing@xxxxxxxxxxx <mailto:mailoutgoing@xxxxxxxxxxx>

mimedefang.


And also enabling quota.

What is the best way to add quota?


Filesystem quotas?


last feature is adding a Global Address Book. Let me explain about it. Let's say In MS exchange server, Whenever users are added, Those names will be available In a Global Address book. Then, No need to add email addresses to client's email programmes such as outlook express or MS outlook.
Can I enable such a feature ?

The MS GAB is basically a LDAP directory just as Active Directory is really LDAP + Kerberos + DNS + M$ extort^H^H^Hensions
