Forum OpenACS Development: Re: Naviserver on Windows - "select failed" when using ns_sockselect

Dear Brian, the interaction with a SMTP server via acs-mail-lite has always been a problem in the Windows version.
I believe that in the "old" ]po[ installer, the system was using Cygwin sendmail. In my installer there's a binary called "blat", a command line SMTP mailer for which also the sources are available (
It is very easy to modify acs-mail-lite so that it uses this tool.
I did that in the past as a paid consultancy for some of the people who used Windows-OpenACS for real.
Hope it helps,
Thanks Maurizio, especially for the pointer to blat.

I'm more concerned about ns_sendmail than ACS Mail Lite, as that is what we use (and it definitely works on AOLserver on Windows). Also, I would be concerned about the ns_sockselect problem, as we have used socket calls in the past.


Just a quick one. Is the server running with administrative privileges?


Yes, it is.
