connection problems to server

Hi,
I have problem with connection to server. I used em client a few years and the last 2 days  em client  send message authentication failure.  The account name and password are correct. 

Hi Petr,

Which email account has these problems? If it’s set as IMAP, you can try deleting the account and recofiguring it in Menu > Tools > Accounts > Add account.
