See original GitHub issue

When receiving email from Yahoo I get this error message:

Fixed the issue by adding valid (could be self signed) certificate to mailin config:

const options = {
    port: 25,
    disableWebhook: true,
    logFile: 'mailin.log,
    smtpOptions: {
        disableDNSValidation: true,
        disableDnsValidation: true,
        disableDkim: true,
        disableSpf: true,
        rejectUnauthorized: false,
        key: 'privkey.pem',
        cert: 'fullchain.pem',
    }
}
mailin.start(options);

My certificates are signed with LetsEncrypt. not sure if self signed would work, but should.

okay just for anyone that might have tried @Kostanos solution to no avail, I do not know if he is using an older version of mailin, but I finally got his solution to work by removing the smtpOptions. in other words:

const options = { port: 25, disableWebhook: true, logFile: 'mailin.log, disableDNSValidation: true, disableDnsValidation: true, disableDkim: true, disableSpf: true, rejectUnauthorized: false, key: ‘privkey.pem’, cert: ‘fullchain.pem’ }

hope this helps someone.
