All of a sudden it appears as though we can no longer send E-Mail by using the mail function in PHP. After doing some investigation through looking at other threads in ServerFault and on various other sites I seem to have determined that sendmail is to blame.
I'm getting this error when I try to reboot it's service.
/etc/init.d/sendmail restart Shutting down sm-client: [ OK ] Shutting down sendmail: [FAILED] Starting sendmail: 554 5.3.5 /etc/mail/sendmail.cf: line 261: service "smtp" unknown: Permission denied [FAILED] Starting sm-client: [ OK ]
I've already tried reinstalling it (yum remove sendmail, yum install sendmail) to no avail. I'm also seeing the following in our /var/log/maillog
Mar 31 03:22:19 xxxxxxxx sendmail: r2VAMJO9002909: to=xxxxxxxxxxxx, ctladdr=nobody (99/99), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30263, relay=[127.0.0.1] [127.0.0.1], dsn=4.0.0, stat=Deferred: Connection refused by [127.0.0.1]
