when customer complain cannot able to email
- need to be root
- check /var/log/maillog
- ps aux | grep sendmail and ps aux | grep postfix
- if 3 shows nothing then need to start the mail service by
- service sendmail start or service sendmail postfix
- TJMNQ and TJMWA use postfix (non standard installation by tom mitch) , other server use sendmail
- run mailq to check outstanding email
- sendmail -q can force the sending of mail in the queue
- check to see why mail service stopped, run chkconfig to see if the mail service is on the list with runleverl 3 set to on if not that mean the service will not get start when restart computer run chkconfig postfix/sendmail on to make it auto start
- service sendmail restart , restart and see if it wrok.
- if not maybe something wrong with DNS , try ping one of the address in the mail queue.
- if it was not pingable then try to ues a different DNS in the resolve.conf. 8.8.8.8 is the google one
- after changing dns best to restart the sendmail. before running the sendmail -q
- if savemail complain cannot save rejected mail anywhere , then it maybe have to do with the permission in /vr/spool/mail directory.
