If I want to send a mail from webmail I receive the next message, what am I doing wrong?

Is it because of the new PHP 5.2.6 or conf settings in PHP.ini?

(disable_functions = passthru, proc_open, proc_nice, proc_terminate, proc_get_status, proc_close, pfsockopen, leak, apache_child_terminate, posix_kill, posix_mkfifo, posix_setpgid, posix_setsid, posix_setuid, furl_open, dl, shell_exec, system, show_source, phpinfo)

Message:
"Forbidden You don't have permission to access /imp/compose.php on this server."

Edit:// According to Plesk: http://kb.parallels.com/en/2278 the disabled functions should be without *exec* or *open* so the disabled functions in PHP.ini should be without: proc_open, pfsockopen and shell_exec ??

Is it safe to remove these functions? Is there a (simple) workarround?

I think Horde uses popen so that must remain enabled. Other than that I don't think you need to enable any of the others. Remember, Plesk uses its own Apache and php.ini so disabling the main web server functions won't impact Plesk.

But why is webmail not sending mail then, this worked before, so somewhere down the line a security setting is blocking this...

popen must be allowed in php else it will fail

But this is open! And still it isn't working it even triiggers a false report on ASL if it fails...
