Devise is driving me crazy

Hi Guys,
Please can someone help me. I have set up sendGrid with devise. I have followed numerous tutorials and done everything correct but after a user signs up the log file site with the following lines:

 Rendering devise/mailer/confirmation_instructions.html.erb
 Rendered devise/mailer/confirmation_instructions.html.erb (Duration: 0.4ms | Allocations: 91)
Devise::Mailer#confirmation_instructions: processed outbound mail in 3.7ms

After what seems like an enternity the actual page redirects on the front end and the log updates with the following. If you look at the Delivered Mail line and the Message ID they contain some crazy random email address with my Macbook name.

Delivered mail 5e7293e497bf4_4b8a3ff2574a84c04004a@Gerards-MBP-2.mail (60180.2ms)

Thanks for your help in advance.

I solved this. I had a default port in my environments.rb file and then localhost was also being declared in my developments.rb which was causing a conflict as it was using port 465 in dev.
