Hello, I'm assming you are running sendmail. If not the procedures will be slightly different but close.
If you have a shell script, simply construct your message either on the fly, or through a temporary file. Then send it to sendmail via a pipe: $ cat <msg> | /usr/sbin/sendmail -f <sender address> <recipient address> Of course for the -f flag to work properly, it should be run as root, if the sender address is different from the current user. If you are doing this out of a C language program, pretty much follow the same steps - but instead of the command line, you'll need to do the normal forks / execs to get a child process going (sendmail in this case), reassign stdin on the child process (I'm going from memory here but this should be reasonably close - in any event you need a mechanism where the parent can write to stdin of the child), and then write the message over the pipe. Close everything down in your program and you're done. Oh, before I forget - make sure that the data you send to sendmail includes both the RFC-822 headers as well as the message body. The sendmail arguments only set the envelope sender and recipient addresses. Hope this is of some help.
