how to send email without password?












1















This might be naive.



But is it possible in Ubuntu to have a script send out emails without requiring passwords? (via a dummy mail server, maybe)



I was hoping to use this to allow my account to periodically send info to myself (a real email account), for example, when certain task is completed. And I don't really want to risk storing the password for a real, external email account on the hard drive.

  • Possibly. My ISP allows me to send mail with the only validation being my sending IP address. ie. I can telnet smtp.myisp.net 25 into their mail server & enter details for email then exit, which of course allowed me to script it & use it for myself. I've even had scripts send externally (not to isp email), but I've also had these rejected (I didn't explore; it was sent externally because of a typo).

Use MSMTP.



MSMTP is a program which delivers email from a local computer to a configured mailhost (mailhub). It is not a mail server (like feature-rich mail server sendmail) and does not receive mail, expand aliases or manage a queue. One of its primary uses is for forwarding automated email (like system alerts) off your machine and to an external email address.

  • This does not address the issue of password storage, since you have to store the password to your account on the mailhub.

  • All modern smtp, requires an authentication, unless you build an SMTP and that authentication is canceled (crazy) or that is open on your network. This option is the best, I think.
