I installed Courier 0.44.2, everything works fine except webmail. When I
send I new message with sqwebmail I receive the following error:
sendmail: ERR: Permission denied
400 Unable to submit message - service temporarily unavailable.
I placed a symbolic link to the Courier sendmail under /usr/bin and
/usr/sbin (same permissions), also the Apache process is a member of the
Courier group. No luck.
I noticed that local users need to be added to the Courier group in order
to to send emails (for example with the mail command) or sendmail
Thanks in advance.
