Some weird postfix stuff I had some weird postfix stuff going on today and so I have written up the following notes. I hope they may be of some use to someone if not just me! Befor you do anything back up a copy of your main.cf file cd /etc/postfix/ cp main.cf main.cf_bk_jun4_clean you can now relax and if need be start from scratch with cp main.cf_bk_jun4_clean main.cf - so we are now safe to test modify and work with the main.cf file (this is the config file for postfix) Run sudo postfix check This should check the various config files for postfix If it can not find the comand double check by using which postfix /usr/sbin/postfix add this to your .bash_profile mine (well part of it ) looks a bit like this PATH=$PATH:$HOME/bin:/usr/sbin log out then log back in (there is a command to automate this but it only takes a few seconds if you use your histroy command) you should now be able to access and or issue the following postfix related commands / tools. postalias postcat postconf postdrop postfix postkick postlock postlog postmap postqueue postsuper To debug stuff open a about 3 terminals to your machine Use one to start check stop and reload postfix using histroy again is a good idea use one to watch your mail log and whats going on tail -f /var/log/maillog or tail -f /var/log/maillog | grep postfix On another you may want to be running postqueue -p Mail queue is empty And if you need to delete stuff from the mail queue postsuper -d [ queue number ] postcat -q [ queue number ] to view the contents of a message Good luck and happy postfixing ! * You will need sudo or root access to issues some of these commands
