The /usr/lib/sendmail and /usr/sbin/sendmail sendmail emulators should work but they just symlink to the path you mentioned. I’ve never had a problem with it (even with perldesk) Pascal, are you getting any errors at all from perldesk?
Well in fact for me it seems to work, as all confirmation mails from perldesk are sent without any pbms. The only problem I have is when I “log a request” from Perldesk directly (from webdesk). It doesn’t send an email to the client and/or the creator of the request.
The support asked me if I use smtp or sendmail with perldesk and if my outgoing mails worked fine (I use sendmail). For me they do.
But, to test if everything is ok, is it possible to send an email from the command line directly using sendmail ?
