A: Make sure Neutron is downloaded and installed from here. Check if e-mail account is listed in Neutron's settings -> Help -> Account. If not, try adding it via OS settings as POP3/IMAP e-mail account. If it does not help, account is already added but Neutron does not see it and Neutron has permission provided to access device accounts, then you could try adding account manually via Help -> Account -> [+]:

For example for 163.com service it would be:

  • Address for POP: pop3s://pop.163.com, or for IMAP: imaps://imap.163.com
  • Username: This email address is being protected from spambots. You need JavaScript enabled to view it.
  • Password: password for This email address is being protected from spambots. You need JavaScript enabled to view it. account in 163.com service

Also make sure that access to the account via POP/IMAP protocol is enabled in the mail service settings:

If Neutron failed to validate (login) the account it will be shown with yellow color in the list. You can disable IMAP/POP3 access for your e-mail account if license check succeeded (when you see red dot on your e-mail account in Help -> Account list). If you reset Neutron's settings you will need to re-do the above steps again.
