I'm running the latest CVS (spellcheck rocks!) and when I send an email, my /var/log/httpd-error.log tells me:
[Wed May 17 09:27:43 2006] [error] [client 199.249.176.251] PHP Warning: Cannot modify header information - headers already sent in Unknown on line 0, referer: https://cryer.us/roundcubemail-cvs/?_auth=8a3fedb6ff5174f02748cce209456e876e...

This only started up recently, let me know if I need to display my php.ini, turn up logging or anything else to help debug.
Thanks
