SME server virus scan notification and double bounce

Tue May 18 16:16:41 GMT 2004 SME server virus scan notification and double bounce

We now have a way to eliminate virus notification and double-bounce messages on SME 6.0. Make sure you have the latest 6.0 blades before doing this.

Double-bounce

Login as root (ctrl-alt-f2 on the console or ssh in)

mkdir -p /etc/e-smith/templates-custom/var/qmail/control
echo devnull > /etc/e-smith/templates-custom/var/qmail/control/doublebounceto
/sbin/e-smith/signal-event email-update
/etc/rc.d/init.d/qmail restart
 

Unknown user notification

Unfortunately, there is just too much "xyz@yourdomain.com" nowadays. It's nice to notify the unfortunate person who mistypes an email address, but we can't afford to do that nowadays.

echo "#" > /var/qmail/alias/.qmail-devnull

mkdir -p /etc/e-smith/templates-custom/var/qmail/alias/.qmail-default

echo "&devnull" > /etc/e-smith/templates-custom/var/qmail/alias/.qmail-default/10devnullbounces

/sbin/e-smith/expand-template /var/qmail/alias/.qmail-default

Set "Forward email for unknown users" to "admin" after doing this.

Virus notification

Ordinarily, three people get notified when a virus is found in email: the admin user, the recipient, and the sender. Nowadays, notifying the sender is probably useless, because it is usually a bad email address. You can turn off any or all of these, but consider that if, for example, your boss sends email from his virus infected home machine to you, you and he will never know anything about it if you have all of these turned off. Consider also that if a machine WITHIN your network gets a virus, you'd never know about that if all these are turned off. The annoyance of these may be enough for you to do it anyway, but at least think about the consequences. It is probably reasonable to turn off Sender at least.

/sbin/e-smith/config setprop scanner EmailAdmin disabled
/sbin/e-smith/config setprop scanner EmailRecips disabled
/sbin/e-smith/config setprop scanner EmailSender disabled 
/sbin/e-smith/signal-event email-update 
 

(My SME customers can request that I do this for them; just call or email)

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
