Hello. I can’t send a single message from any mailbox, it always gives an error: Error sending message Error sending message. The message could not be sent because it was not possible to establish a connection to the outgoing mail server (SMTP) “smtp.mail.ru.” The server may be unavailable or - SMTP. Be sure to specify the correct outgoing mail server (SMTP) parameters and try again .

What are your settings? They recommend smtp.mail.ru on port 465, SSL/TLS security, User Name = email address. If the incoming server is IMAP, it's possible to use OAuth2 authentication for the incoming and outgoing servers, instead of 'normal password'.

В общем я выяснил что блокирует отправку сообщений мой интернет. Что мне делать? Какие-то порты открыть надо, или как?

In general, I found out that my Internet is blocking sending messages. What should I do? Do you need to open any ports, or how?

You may have to allow TB through your firewall, but most cases of blocked sending are caused by security or antivirus programs that are set to scan outgoing mail.

Я просто взял свой компьютер и подключил его к другой сети интернет, и все заработало, не антивирус, не брандмауэр не блокируют исходящие сообщения. Это именно интернет, так что в нем проблема

I just took my computer and connected it to another Internet network, and everything worked, not an antivirus, not a firewall, they won’t block outgoing messages. This is the Internet, so there’s a problem

Maybe the other network doesn't support ipV6. Edit/Preferences/Advanced/General/Config. editor and double-click the preference network.dns.disableIPv6 to true, restart TB, and see if it makes any difference.
