Sorry for the delay in replying - glad you’ve gotten your Sendmail config generating correctly now at least. I’m afraid I can’t really help you much further though, sorry. I’ve got no experience myself in setting up Sendmail to do what you’re trying to do, as I’ve never had to set up a Sendmail box to do quite what you’re trying to do.
From some Googling it seems it’s certainly possible to get Sendmail to talk to an MSA rather than an MTA and authenticate against it using the authinfo mechanism previously discussed, but as you say you might need to get TLS and other things besides working for this to operate correctly. Perhaps others who have gone down this road and are reading this thread could advise you on how to proceed, if this is really something you absolutely have to do.
On that subject, though: again, is there a reason you have to do this, and pass the mail on to a server that is normally used for talking to mail clients and whatnot ? Why can’t you just straight send this mail to its correct destination from your local server, without a relay or smart host or anything else in the way ? Or alternatively, is there not a mail server on site that already is set up to do e-mail correctly that you can just use as your smart relay, saving yourself all this trouble ?

Our domain is techx.com however
does not have any smtp service like smtp.techx.com. Infact techx.com domain is actually provided by same zoho.com.

I m not sure how to setup using this approach. Any guide / link with step by step approach for Linux centos 7 in this regards would be appreciated. All i need is the outgoing emails from my linux server to work.

NAME
calibre-smtp - part of calibre
SYNOPSIS
calibre-smtp [options] [from to text]
DESCRIPTION
Send mail using the SMTP protocol. calibre-smtp has two modes of operation. In the compose mode you specify from to and text and these are
used to build and send an email message. In the filter mode, calibre-smtp reads a complete email message from STDIN and sends it.
text is the body of the email message. If text is not specified, a complete email message is read from STDIN. from is the email address
of the sender and to is the email address of the recipient. When a complete email is read from STDIN, from and to are only used in the SMTP
negotiation, the message headers are not modified.
Whenever you pass arguments to calibre-smtp that have spaces in them, enclose the arguments in quotation marks.

--version

-h, --help
