I don't think so. NAVIEG will accept everything on port 25, scan it, and
forward to Imail's port. Since NAVIEG is your MX receiving all incoming
traffic, your local users SMTP AUTH commands hit NAVIEG:25 and not
Imail:1875. And NAVIEG doesn't know how to do SMTP AUTH (nor "relay for
addresses" so it's an open relay, too, the dumb@ss, but I think they were
going to fix that) since NAVIEG would need to access Imail's account
database to obtain the Imail user's ID and password for the SMTP AUTH
process. If Imail and NAVIEG were both using the same external database,
then NAVIEG could do SMTP AUTH. Does NAVIEG support external user
databases like NT database or ODBC or even SMTP AUTH with the various
encryption schemes?
Wouldn't it be great if Imail supported external LDAP or radius
servers? (ipswitch has no plans)
If mail client programs allowed sending outbound SMTP traffic to
ip.ad.re.ss:port, then you could tell your users to send their outbound to
Imail:1875 so at least they could send out and you could do SMTP AUTH for
anti-spam.
I just checked here for Eudora : http://www.eudora.com/techsupport/ini.html
... and you can set the "default SMTP service port" to whatever in
Eudora.ini (ha, won't your tech support telephone monkeys have fun with
that one!! "use notepad for your .ini file" "sorry, I all I have handy is
post-it notes. can I use that for any file?"). So your Eudora users could
use SMTP AUTH to Imail:1875 but their mail would not get AV scanned,
assuming Imail would then deliver the outbound mail to Internet and not
NAVIEG port.
Except maybe if you have Imail SMTP "send all mail through a gateway" where
the gateway was the ip of the NAVIEG machine. So NAVIEG would receive SMTP
AUTH'ed outbound mail from Imail, scan it, and deliver it to ultimate
destination.
hey, all of this is "hypothetical big picture" that you need to verify with
NAVIEG and Ipswitch. But let us know what you find out.
I really think all of the above is less simple, less failure-prone, and
slower than having NAVIEG on its own dedicated machine. NAVIEG and Imail
both live a :25 like normal people and the NAVIEG scanning (read file from
disk, decode (back to a disk file?), scan, encode (from a disk file?),
write file to disk) suck up all the CPU and disk capacity leaving Imail
with much less to run with.
