Hi List,

I noticed that some spammers have found a workaround for the sanitycheck
in qmail-smtpd. I most cases it works just fine, e.g.

220 mail0.speakeasy.net ESMTP
helo
250 mail0.speakeasy.net
mail from: user
554 mailfrom without @ is administratively denied

But if I don't give it anything, it accepts the mesage, this is not good.

220 mail0.speakeasy.net ESMTP
helo
250 mail0.speakeasy.net
mail from:
250 ok

-- or --

220 mail0.speakeasy.net ESMTP
helo
250 mail0.speakeasy.net
mail from: ""
250 ok

I am not able to adjust the regext rules in qmail-smtpd.c, but I am
hoping someone will know how to solve this problem.


Andreas
