I have just sent a mail, can you check if mail has gone? A user ask me....Opps...How can i check this? which file should i check first?


Yeah, there many case when you need to check if mail has gone or not? Here qmail Log files which you need to check.


vi /var/qmail/supervise/qmail-send/log/main/current | tai64nlocal

this file logs all send mail & using tai64nlocal you can convert qmail log time to local time zone.
