Switch work email from macbook pro to new macbook

[specialkdj]

I have been using a macbook pro for work, work emails and DJing.
Recently I decided to get a new macbook solely for work and work emails.

I have my work email account set up in "mail" on my macbook pro and it is working without a glitch.
I'm facing 2 difficult issues on my new macbook.


Issue 1
After setting up my email account on my new macbook, every few seconds a pop up will appear prompting me to:
"Enter password for xxxxxxxx"

"The POP server “mail.xxxxxxx.com.” rejected the password for user “xxxxxxx@xxxxxxx.com”
Please re-enter your password, or cancel."


Issue 2
From the macbook I tried sending a test mail to the very same email account.
I received the test mail on my macbook pro but not on my macbook.
So the outgoing works fine but incoming isn't.

What email service are you using?

Are you sure you have the correct password in the mail account settings? Check you KeychainAccess.app on the MBP to be sure.
