does this work? you should use SMTP client like 'msmtp' instead.

Each website has it's own SASL authenticated account and mail are sent via

But, some website doesn't verify email existence when a user submit a web form

Thanks for the response. Two questions:

2) I've read the man page, but it isn't clear in whether I can

program? For example, whether postfix can read
