Troubleshooting mail() and sendmail

Does anyone have any tips for general troubleshooting of mail()? The standard *nix "mail" command works fine from the command line, but php scripts that use php's mail() run very slowly -- then the mail ends up not getting send. I assume I have something misconfigured for sendmail but am not sure where to begin looking. I am running php 4.3.1 on RH 8.0. output of phpinfo() follows.
