AUTH USING IN TELENET COMMAND

Yes, but the key is that if swaks works, the KumoMTA instance is working.

Can you please tell me some work aroud for this, As, every of my clients can not use swaks

for testing they will use onlince base64 encoding tool

Will they though? Most users have an app they want to connect, they will enter their credentials into the app, check to use TLS, and click Send Test. Or they built code with a SMTP send function that they will pass the credentials into and send. Telnet testing is common for those setting up and MTA, not so much for those looking to use it.

ok now worries could you be tell me how can I set mail from in swaks
