Учётная запись POP3 работает корректно в Thunderbird, и её конфигурация успешно определяется автоматически.
Однако Discourse не может её активировать, несмотря на временное решение для TLS 1.3.

Эту ошибку можно воспроизвести с помощью чистого Ruby Net::POP3, но аутентификация не завершается неудачей. Это просто бессмысленная ошибка OpenSSL. Подключение напрямую через openssl s_client работает как для TLS 1.2, так и для TLS 1.3. Я не уверен, что делать, поскольку всё, кажется, работает нормально, за исключением предупреждения OpenSSL в момент разрыва соединения.
Вот минимальный тест на Ruby:
Тест Net::POP3
require 'net/pop'
puts "Testing POP3 connection for #{ENV['POP3_USER']} on #{ENV['POP3_HOST']}"
Net::POP3.enable_ssl
pop = Net::POP3.new(ENV['POP3_HOST'], 995)
print " using SSL: ", pop.use_ssl?? "yes":"no", "\n"
begin
pop.auth_only(ENV['POP3_USER'], ENV['POP3_PASS'])
puts "Authentication succeeded!"
rescue Net::POPAuthenticationError => err
puts "Authentication failed."
# p ENV['POP3_USER']
# p ENV['POP3_PASS']
# p pop
exit
end
Обратите внимание, что я также тестировал установку ssl_params для enable_ssl со значениями:
min_version: OpenSSL::SSL::TLS1_3_VERSIONmax_version: OpenSSL::SSL::TLS1_2_VERSION
с теми же результатами.
Вот сеанс OpenSSL (одинаковый для TLS 1.2 и 1.3):
openssl s_client -quiet -tls1_3 mail.example:995

Интересно, почему другие реализации не выдают эту ошибку OpenSSL.
Я думаю, что это ошибка в Stalwart-mail, и я сообщу об этом в данной теме для рассмотрения.
