My problem is when nagios is sending email notifications it includes the entire hostname in MAIL FROM field (i.e. <A href="mailto:nagios@hostname.domainname.com">nagios@hostname.domainname.com</A>). There is no problem when I send an email using PINE from nagios user, so my sendmail is configured properly. This is a problem for me because some email servers lookup the MX record of the domain name and refuse email if it does not match. ADMINEMAIL in nagios.cfg is <A href="mailto:nagios@myrealdomainname.com">nagios@myrealdomainname.com</A>, but nagios still puts the hostname in the FROM field. Could anyone tell me where I can configure it? Thanks, Val </BLOCKQUOTE></DIV></BLOCKQUOTE></BODY></HTML>
