Forum OpenACS Q&A: Re: ecommerce module &amp; qmail ... still a requirement?
don't you think that those users who switch to a faster MTA than ns_sendmail have enough know how to replace ns_sendmail with the MTA of their choice? Whether that be qmail, postfix, courier or another one of the multitude of MTAs.
I prefer to keep the code clean and free from legacy snippets that are commented out. Especially when the commented code only pertains to one of many possible implementations.
However, for those who would like to keep using qmail, the patch is in http://cvs.openacs.org/cvs/openacs-4/packages/ecommerce/tcl/qmail-procs.tcl.diff?r1=1.3&r2=22.214.171.124&f=h
