Re: [vchkpw] pop-before-smtp and chkuser
There is no need to change the code...
Once you've enabled
#define CHKUSER_RCPT_LIMIT_VARIABLE CHKUSER_RCPTLIMIT
it's enought you declare this variable CHKUSER_RCPTLIMIT with the limit
you want before running qmail-smtpd.
So add a
export CHKUSER_RCPTLIMIT=50
before running qmail-smtpd (and be sure it can see this variable);
