then in https://passport.yandex.ru/profile check if app passwords or two-factor authentication, if something of this is included, then generate for The Bat! an application-specific password and use it for POP3/SMTP instead of the primary password for the account. - Robb45 commented on June 8th 19 at 17:02
For third-party applications 100% off - after switching on, nothing has changed
At the expense of two-factor authentication off, because I am comfortable with your old password go to the browser without additional passwords - Thelma64 commented on June 8th 19 at 17:05
then disable the app password (or leave it enabled and generate an app password is more secure) and check the POP3 settings in The Bat! connection must be via SSL or TLS. - Robb45 commented on June 8th 19 at 17:08
After a couple of days all by itself to work (settings are not touched). Don't know what happened. But one PC out of 4 anyway remains this error(( - Thelma64 commented on June 8th 19 at 17:11
in POP3 it is impossible to make more than one connection at a time. Or, go to the IMAP or reduce the interval of collection letters and make it different (and better not a whole number of minutes) for each customer. Have The Bat! has this peculiarity that he always checks the mail in the first second of the minute, so multiple clients talking at the same time. - Robb45 commented on June 8th 19 at 17:14
