> .I badmailpatterns
> Gives

> the ability to filter E-Mails by comparing the sender

> Example:

> .EX
>   *@earthlink.net
>   !fred@earthlink.net
>   [0-9][0-9][0-9][0-9][0-9]@[0-9][0-9][0-9].com

> .I badmailpatterns
> file with this contents stops all mail from Earthlink except from
> fred@earthlink.net. It also stops all mail with addresses like:
> 12345@123.com and answerme@savetrees.com. Further, any E-Mail with       
> a sender address containing a percent sign (%) is rejected.
> .TP 5
> .I badrcptto
> Unacceptable envelope recipient addresses.
> .B qmail-smtpd
> will reject every incoming message
> if the envelope recipient address is listed in
> .IR badrcptto .
> This control file is complementary to
> .IR badmailfrom .
> A line in
> .I badrecipient
> may be of the form
> .BR @\fIhost ,
> meaning every address at
> .IR host .
> .TP 5
> .I badrcptpatterns
> employes the same filtering logic for the envelope recipient as
> .IR badmailpatterns .
> It allows

>   *\\[dd.dd.dd.dd\\]*
