Hi @Mailit2me
No success despite using the alternative settings, as @steveshank asks, have you tried all 3 IMAP options?
Have you tried disabling anti-virus (particularly AVG/AVAST) and VPN if used?
I guess from what you say that you have had similar problems with other email clients, are you able to use email with a web interface via your browser?
Are you in UK?
I have seen Plusnet adverts on Sky here in Spain; they state that they have ‘REAL’ people to talk to in support, have you tried them?
Have you tried to connect using POP3?
And you should use a manual set up not automatic if you do.
¡Saludos desde la soleada España!
