How to configure DU Meter email notifications feature?
DU Meter can deliver alert notifications via e-mail only if you provide the particulars of your e-mail server correctly.
Configuring DU Meter email notifications for use with your ISP or corporate email server.
Please consult your ISP support or corporate IT staff for the name of SMTP server. Sometimes you can guess the name of the SMTP server from your email address. E.g. if your email is firstname.lastname@example.org, then the SMTP server typically (but not always) is mail.example.com or smtp.example.com. Port should nearly always be 25, and username and password should be left empty.
Configuring DU Meter email notifications for use with Gmail, Hotmail or other online email services.
If you use Gmail, set the SMTP server name to gmail-smtp-in.l.google.com and port to 587. Encryption should be left at Auto or set to TLS. Please note that SMTP encryption is supported in DU Meter 6.0 and later only.
If you use Hotmail, set the SMTP server name to smtp.live.com and port to 587. Encryption should be left at Auto or set to TLS. You'll also need to enter you Hotmail username and password. Please see this Microsoft acticle for more information.
Please note that if you use either Gmail, Hotmail or other free email service with DU Meter and you don't supply that service's username and password to DU Meter, then the recipient's email address must belong to that service. E.g. you can only use Gmail to send alert notifications to \@gmail.com address.
If using online email services in DU Meter produces "time out" errors, most likely your ISP is blocking outgoing email using any SMTP service other than that ISP's. In that case, configure DU Meter to use your ISP's email server.
