After updating to MailStation-20100317-017 on the 2.3 firmware I get this error sending mail from RoundCube:
SMT error (-1): No connection with the SMTP server (not the exact message, translated from Dutch).
My SMTP server is set to 'localhost' in the DiskStation Manager.
Running some checks I discovered the postfix process is not running:
postsuper: fatal: scan_dir_push: open directory defer/D: Permission denied
I am not a Unix/sendmail expert but I think this is a problem....
Please let me know your opinion and possible solutions.
