Title: transparent smtp proxy in 6.0b3
Post by: Michael Soulier on October 27, 2003, 10:37:38 PM

Many users have been unpleasantly surprised by the new transparent smtp proxy in 6.0b3, and have looked for a way to turn it off. To that end, please test the following rpms, found in my contrib
area on our mirrors later today.

e-smith-email-4.14.0-06.noarch.rpm
e-smith-mailfront-1.3.0-09.noarch.rpm

Install like so:

rpm -Uvh *.rpm
/etc/e-smith/events/actions/initialize-default-databases
/sbin/e-smith/signal-event remoteaccess-update
/etc/e-smith/events/actions/restart-masq

Now, you should have a "Proxy" property in your "smtpfront-qmail"
record in the configuration database. It is enabled by default. The
following will disable it.

/sbin/e-smith/config setprop smtpfront-qmail Proxy disabled
/sbin/e-smith/signal-event remoteaccess-update

Obviously, it can be reenabled again just as easily.

Please report any problems to smebugs@mitel.com.

Thanks,
Mike

please excuse my ignorance, but what are the advantages or disadvantages of the transparent proxy?

The advantages are that you force all outgoing smtp to go through the server, thus being subject to any limitations you place upon outgoing mail, and (in the commercial release) virus scanning. As many recent viruses have relied on emailing themselves out to infect other machines, this feature can be used to prevent such propagation.

As we cannot assume that everyone's needs are the same, we do our best to keep the server flexible. It always was, mind you, via the custom templates, but this solution is friendlier.

Regards,
Mike

Thanks for the addition! Having a server in China it's really not wise to use the transparent proxy. If this contrib now gets included into the "services" contrib (can't be difficult, can it?), then my life would be perfect...

It's not a contrib. It's development code for the server.

But what appens if there's an update... we will have to wait that you build the correct rpm? Or these setting will be able in next versions/updates ?
