Actually, I do not seem to have the same problem. I don't get the broken pipe error, nor do I get any error in FS log or console (the error message in log disappeared after some upgrade but I don't remember which). However, what I can tell is that I get the problem as root AND as non root. I can also tell that sending the exact same message with the exact same command line as my freeswitch user work (sudo -u freeswitch cat savedmail | sendmail -f freeswitch@mydomain -t some.user@mydomain). This does not seem to be an environment problem either (I could not seem significant differences between the 2). I'm about to strace what happens too.

You're right maybe it's a thread child problem. I saw there is a windows condition already in your code ? and for mac it should work since ssmtp is in standard in all package, even for solaris and hp-ux.

I am still wondering if it's a stack size running out issue in the child thread from system. Are you running FS as root or as a non-privileged user, i'm wondering because maybe if its a regular user, its not able to increase the stack size up to 8megs maybe you can push in strace into the command so it will show why it breaks.

So the robustest solution is to replace sendmail by ssmtp (yum install ssmtp or apt-get ssmtp etc...) configure /etc/ssmtp/revaliases and /etc/ssmtp/ssmtp.conf, change the switch.conf.xml like this and apply the patch attached (no choice since it needs filename as argument and not STDIN). hope it will help people who have sendmail segmentation fault problem.

Would you consider making a script that mimics the current behavior of a mailer app and read the file from stdin and deliver the subsequent file so it is backwards-compatible with the way everything already works?
