Я устанавливаю Sendmail на ящик Debian. Я пробовал дважды, и каждый раз получаю ошибку отложенного подключения. Я выполнил следующие процессы:
apt-get purge sendmail*
apt update
apt install sendmail sendmail-cf m4
sendmailconfig (I answered Y to all)
sendmail -vt < ~/mail.txt (FAILED)
nano /etc/mail/local-host-names (added web1 and web1.mydomain.com)
m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
service sendmail restart
sendmail -vt < ~/mail.txt
Содержимое hostnamectl:
root@web1:~# hostnamectl
Static hostname: web1.mydomain.com
Icon name: computer-vm
Chassis: vm
Machine ID: bf9dd17320f042e1b8715468578181b6
Boot ID: 8981063e23dd4c07905ea630f2ab0a75
Virtualization: kvm
Operating System: Debian GNU/Linux 10 (buster)
Kernel: Linux 4.19.0-9-amd64
Architecture: x86-64
И содержимое / etc / hosts
127.0.0.1 localhost web1.mydomain.com
213.168.250.175 web1
Мое сообщение принято Sendmail для отправки, но никогда не завершается. Обычно эта проблема может быть связана с ошибкой telneting-порта 25, но я проверил это и прошел успешно.
Вот результаты, когда я запускаю команду sendmail:

Почему мне откладывается соединение? Я просто не могу понять, что еще могло вызвать проблему.
