I tried everything that I could do as per knowledge. I tried the following-
As per the suggestion by https://www.hostinger.in/tutorials/smtp-port-587, I disabled firewall by "sudo ufw disable", Checking with ISP (although the same problem occurs with different ISPs). As per the suggestion by http://ubuntuguide.net/install-and-enable-telnet-server-in-ubuntu-linux, I installed telnet server and made every change as suggested except step 5 (I couldn't find that file). Checked if IMAP is enabled on my gmail service. Now I have no more ways to try to resolve the issue. Any help or suggestion is appreciated.
