How To Configure mdadm RAID e-mail Notifications via ISP SMTP Using msmtp

[fermulator]

I know this post is old and probably no one really monitors it however I keep getting this error when trying to test my email as described in the first post. msmtp: /etc/msmtprc: line 49: account Gmail not (yet) defined

I did change my password to the app specific password as described earlier as well. When I go into the mail logs, I see this
Mar 24 02:53:38 server-box postfix/sendmail[4354]: fatal: open /etc/postfix/main.cf: No such file or directory
Mar 24 08:25:57 server-box postfix/sendmail[1132]: fatal: open /etc/postfix/main.cf: No such file or directory

Could this be because I have postfix installed? I could remove it as I haven't yet gotten it set up for anything.
Any ideas?

Sorry never tested w/ postfix ... did you miss the "sendmail symlink" trick I noted in the tutorial?

When postfix is missing the main.cf it means that the config has not yet been run. Don't bother re-installing it simply run

sudo postfix dpkg-reconfigure

I actually ended up using another SMTP mail sender. It worked pretty well. If I can find the link again I will post it here. Postfix seemed to be harder to set up. I have already gotten emails on changing file sizes as well as a crap line in fstab. Fixed fstab and haven't gotten any other emails since. Apparently it gives me what I was looking for. Thank you for taking the time to answer this old question thought. I appreciate it. Maybe I will give it some time and work with postfix.
