I have an Debian linux SMTP server that is aliasing
(using exim) two exchange email domains.
mail into one name and relaying it on to the exchange
servers.
(ex.
Exchange1=>newdomainSMTP=>internet
internet=>newdomain=>SMTPExchange1
Exchange2=>newdomainSMTP=>internet
internet=>newdomain=>SMTPExchange2)
Question: Is it possible
As you're rewriting the recipient addresses, the recipient validation will not work. You can however turn off this option if you want. NMS ships with postfix and you might also prefer to rewrite the addresses using postfix instead. If you're doing some recipient validation on your exim config using aliases you can omit postfix, but then you loose the antivirus check as performed by clamsmtpd. However, it \*is* still possible to enable an alternative AV check in assp, but it's not as advanced as clamsmtp. For instance it will not check viruses in archives and the signature db is also of an old format.
Question :If I use NMS as a standalone device can i
use SMTP linux box for the LDAP?
Question: do i need to have a Kerberos config on the
SMTP linux box?
For recipient validation NMS uses LDAP. It should be possible to use openldap or something like that as well, but I have not tried it.
For management authentication NMS relies on LDAP+kerberos as shipped by AD. It's probably possible to set these services up in Linux as well, but I have not tried it myself.
Question :Can I setup the appliance to pass mail to
the SMTP server?
Yes.
An update of this virtual appliance should be available shortly. I will get back here with details.
