On Friday, I stopped downloading the mail program from o2.pl mail server. After refreshing, a message pops up: “ERR failed mailed to fetch eml”. Sending messages is done correctly…
Configuration changes, reinstallation of the program and removing accounts did not help to solve the problem.
I will add that “gmail.com” downloads messages without any problem.
Question, how to solve this problem? On the second computer I have the same problem with an email based on the o2.pl server
I attach photos.
