I am not sure if this is a correct platform to ask but as I find this question almost similar to my problem, that's why I am posting it here.
I have a mail account set at [email protected]. But the server mail.institute is not accessible from outside the institute's network, except for a dedicated frontend website they plugged in.
The problem is I cannot sync that mail account in my Mail client apps like Thunderbird, Gmail, outlook etc. unless I am inside the Institute.
The specifications that works for mail clients (Gmail App) inside campus:
Incoming Setting: server: mail.institute, port: 143, security: None.
Outgoing Setting: SMTP server: mail.institute, port: 587, security: STARTTLS.
Luckily, they provide a machine say A, which is accessible from outside (thus we can access any machine inside institute using ssh after ssh-ing this machine A) .
Can I setup some settings in some existing mail clients (say Thunderbird, but Android settings is more preferable) which will transitively use machine A to sync my mails from outside the campus?
