SMTP problem

[Kaj-IN]

Hi,

I have a problem with smtp notifications and still got error result "self signed certificate".

or

docker logs 58f720e88xxx | grep Error

Error: self signed certificate
at TLSSocket.onConnectSecure (_tls_wrap.js:1515:34)
at TLSSocket.emit (events.js:400:28)
at TLSSocket._finishInit (_tls_wrap.js:937:8)
at TLSWrap.ssl.onhandshakedone (_tls_wrap.js:709:12) {
code: 'ESOCKET',
command: 'CONN'
}

The current SMTP configuration is:

If I try to send emai via telnet everythning goes well:

└─# telnet email.prahax.cz 25

I'm having the same issue. Can we please allow self-signed certs? Maybe a checkbox to allow self-signed certs?

Seeing this too, I told it to "Ignore TLS error" but it doesn't seem to be. I can't get SMTP to work otherwise, even if I put in port 25 (it shouldn't be trying TLS!)

Looking at the docs, sendMail() might be the wrong place to set rejectUnauthorized. The method in the docs only has data as a parameter, whereas the tls option is set in the transport config. I don't have a mail server to test this tho.
