1.) User Information: Your username or Email address should be proper , otherwise use of wrong email address mostly occur the failure demon reasons for emails.

2.) Server Information: According to your account (POP3, IMAP, SMTP), you should fill the right server information:

Incoming server Information: Like this (pop.gmail.com)
Outgoing Server Information: Like this (smtp.gmail.com)

3.) Click on the “More Setting” option and within the new pop-up window also check your Server Port Numbers which come under the “Advanced” option.

Default incoming server port number for POP3: 995
Default outgoing server port number for SMTP: 587


Check the same settings at the Gmail end and make necessary changes if something wrong. Hope this will work.



Thanks
