Oct 9 11:42:03 localhost sendmail[3080]: NOQUEUE: SYSERR(apache): can not chdir(/var/spool/clientmqueue/): Permission denied
–

First you have to check if permission are correct. Here is the permission below in my system

# ls -l /usr/sbin/sendmail.sendmail -r-xr-sr-x root smmsp /usr/sbin/sendmail.sendmail

# ls -l /var/spool/clientmqueue drwxrwx— smmsp smmsp /var/spool/clientmqueue

If your permissions or ownership is wrong then change it using chown and chmod.

If the above is right then disable selinux or if you want selinux enabled use chcon to set the correct selinux context.

Selinux may cause the issue, to verify run:

getsebool -a | grep mail

If it displays as bellow it is selinux:

allow_postfix_local_write_mail_spool –> off

You may disabled it, but if you want to keep it (and you should as it provides an extra layer of security) you should do something else:

setsebool -P httpd_can_sendmail on

This will allow the httpd to send emails, as when you use php mail().

И починилась

Hate to necro this, but none of the solutions here worked for me. I know very little about SELinux, but I ended up discovering the problem with this (on CentOS 6):

getsebool httpd_can_sendmail

Which told me it's disabled. Fixed with

setsebool httpd_can_sendmail 1
