Hi and welcome to the site, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.

Initially, when was the least time you were able to send an email successfully to her?

Are you able to send emails to others with no "Mailer-Daemon" issue?

Customer: replied 10 months ago.
The Mailer-Daemon started on October 28th and I thought I would wait it out so I emailed her again and the time at November 1st it just popped up again and it's only her I'm having trouble sending emails to her. Before the day October 28th the emails were sent successfully but then it's just went to that Mailer-Daemon

How do you open/send emails? using Chrome, Firefox, email client/program?

And have you tried to contact your girlfriend by any other means? ...SMS/text, phone call, Skype, IMs?
