SquirrelMail: 127 Can’t execute command

··69 words·1 min·
Php Plesk Sendmail Squirrelmail

I found a Plesk 8.3 server running RHEL 4 last month that was presenting errors when users attempted to send e-mail via SquirrelMail:

ERROR:
Email delivery error
Server replied: 127 Can't execute command '/usr/sbin/sendmail -i -t -fsomeuser@somedomain.com'.

The error was appearing because safe_mode was enabled and SquirrelMail was unable to drop e-mails into /usr/sbin/squirrelmail. After disabling safe_mode on the server, the users were able to send e-mails via SquirrelMail.
