Okay, I found /etc/cron.daily/exim4-base which seems to be the script that is running each morning. I'm not really that smart in reading these scripts. I find the mail command and the subject line. What I don't seem to find is the TO: line. I do see references of $E4BCD_DAILY_REPORT_TO which may be the TO: string, but I can't find that variable defined. I find these declarations at the beginning of the script:
E4BCD_DAILY_REPORT_TO="" E4BCD_DAILY_REPORT_OPTIONS="" E4BCD_WATCH_PANICLOG="yes" # Number of lines of paniclog quoted in warning email. E4BCD_PANICLOG_LINES="10" E4BCD_PANICLOG_NOISE="" but those are empty strings. I did move the exim4-base script out of the cron.daily folder which, I hope, should stop the outgoing emails. I do need to get this mailserver working again. Is exim4 still a good choice? Anybody recommend a good tutorial on it? I haven't worked with mailservers since about 2005 so I'm a bit rusty and need to get caught up on current practices.
