Anyone know otherwise? Anyway, the current implementation does the following (just do you know): 1. creates temporary file /var/mail/xmit<pid> 2. accept message until trailing period 3. close temporary file 3. fork 4. open temporary file as stdin 5. exec: /usr/sbin/sendmail -t -oem 6. wait for child exit 7. delete temporary file unless in debug mode Note that sendmail will read the /etc/sendmail.cf file, even in this single message mode. Seems like there are some security issues here. Of course the POP connection is authorized before this can happen, but we'll have to think about the implications of having direct access to /usr/sbin/sendmail.
