I'm running tinytiny RSS on OpenBSD httpd with PHP-FPM and MariaDB. In
order to get mail working for it, I also needed these copied from their
usual places into the /var/www chroot:
/var/www/usr/sbin/sendmail
/var/www/usr/lib/libutil.so.12.1
/var/www/usr/lib/libc.so.80.1
/var/www/usr/libexec/ld.so
/var/www/etc/resolv.conf
/var/www/etc/hosts
Hope this helps.
