I am having trouble setting up email ticket creation. I have the email setup in what appears to be a valid config and setup the cron job which seems to be running. However cron was outputting the following:
Jun 17 18:05:01 servername CRON[2205]: (www-data) CMD (/usr/bin/php /var/www/osticket/include/cli/modules/cron.php)
Jun 17 18:05:01 servername CRON[2203]: (CRON) info (No MTA installed, discarding output)
Email sending was working but I wondered if I needed to install an MTA because this is on Ubuntu which I don't think has one by default so I installed postfix. I configured it with no config because this shouldn't be necessary for fetching. now I receive the following cron log:
Jun 17 18:10:01 servername CRON[3138]: (www-data) CMD (php /var/www/osticket/include/cli/modules/cron.php)
Jun 17 18:10:01 servername cron[961]: sendmail: fatal: open /etc/postfix/main.cf: No such file or directory
Jun 17 18:10:01 servername postfix/sendmail[3140]: fatal: open /etc/postfix/main.cf: No such file or directory
Jun 17 18:10:01 servername CRON[3137]: (www-data) MAIL (mailed 103 bytes of output but got status 0x004b from MTA#012)
Is postfix necessary to pull IMAP (it seems to me that it shouldn't be). If not, any thoughts on why the cron job is complaining about the lack of an MTA?
