How can I send email with SMTP and SSL/TSL

[mdobydullah]

Hello.

Currently, I can send email with SMTP (port 25). I tested with https://www.smtper.net. It works. Now I want to send email with SSL/TSL (465 or 587). How can I do it?

I've installed SSL and changed port 25 to 587/465 in postal config file but doesn't work. Mail server fails to send if I tick "Use Secured Connection" on https://www.smtper.net.

From postal admin panel, if I send email from "send message" page, it sends with SSL.

Thank you.

Hi @hswamy,

Sorry for late reply. I was out of work. I didn't check GitHub during vacation.

Hi @acsfer,

Yeah sure. We should also wait for response. We don't know the current situation of each person.

We can also use issue search option. Sometimes we get solution from other issues.

Thanks.

Thanks for the response @mdobydullah , I went through your issue solution and I checked the smtp logs and i see permission denied as below.

Any idea ?

I gave read permission to .key and .crt file,

But still if i use -UseSSL, i get an error saying Send-MailMessage : The remote certificate is invalid according to the validation procedure

Sorry @hswamy. I don't have any idea. You can take a look at their docs.
