Tsocks with mail user agent mailx not working

Question

I use a SOCKS proxy server to send mail using sendmail in Linux and mailx to send mails from the command line.

To make use of the SOCKS server, I am using tsocks to send mails using mailx, for example like this

tsocks mailx -s "Test mail" valid_mail_address@gmail.com

But the mails I send are not going through the proxy. I don't know what I do wrong.

Any help please.

Answer 1

I suspect mailx is configured to use sendmail so tsocks is redundant here. What happens if you omit it?

tsocks may actually be in the way - if you don't have a rule in /etc/tsocks.conf to bypass the proxy for the loopback interface it could send the message to the proxy when it shouldn't.
