I wanna use gmail with pop3 protocol so:
If I configure the account with gmail button (I mean I add a new account and I use the gmail wizard to add the account).
When a popup ask me to give access to incrediamil and I do, then on incredimail side I've to change the server because are wrong, so I follow this guide https://support.google.com/mail/answer/7104828?hl=en
I see that the password that incredimail show (the asterisk, is very long, my password is shorter but I followed the popup to allow access to incrediamil, so I think is ok)
Till here, not normal but ok, I can do it. Then I try to send and receive mail, but here the 1st problem, I can't receive any mail and I can only send email!!!!!!!

But all is correct, note that I can send email!!!!
Then I delete the account and I create a new one, but instead use the gmail wizard I use the "custom" one.
At the end I've to change the username because @gmail.com is missing, not a big deal, so I end up with the account configured with right port and servers but when I try to send and receive email I got the second surprise, I cannot send email!!!!!!

I receive all email but I can't send email!!!!!
What I can do?
