Webmail Login + Send problems

kram@

Regular Pleskian
Hello,

Using Roundcube:
No users can login.

Error message:
Invalid request! No data was saved.


Using Horde:
users can login but can not send email.

Error Message:
There was an error sending your message: Failed to open sendmail [/usr/sbin/sendmail] for execution.

Plesk Version: Plesk 11.5.30 Update #9
 
Seems obvious enough - check that you have /usr/sbin/sendmail with proper permissions (that allow execution). You may also want to check webmail logs for additional info (somewhere in /var/log, IIRC).
