sendmail 8.14.1

I want to reduce backscatter spam and subsequent double bounces. To
start with i took an approach of reducing the backscatter itself so
configured our domain with SPF information hoping that the spam
bounces would reduce. I think this has had a very slight positive
effect.

the DoubleBounceAddress initially was postmaster but to get it to go
to null i read on the Sendmail web pages on that if this resolves to
an empty string these will get trashed so now i have this in my
sendmail.cf

# where do errors that occur when sending errors get sent?
O DoubleBounceAddress=


- How can i test if this is working correctly?

Regards

James

define(`confDOUBLE_BOUNCE_ADDRESS', `/dev/null')dnl

in the sendmail.mc and rebuild the sendmail.cf, then restart sendmail.

You require this setting in sendmail.mc, remember to remake config and
restart sendmail

define(`confDOUBLE_BOUNCE_ADDRESS',`')
