SMTP connection fails

Andriy Moraru 2020.10.03 21:36

I am trying to switch my MT5 to a new mail server and I am getting weird errors when I test the email settings.

I had no problem connecting to this mail server and sending emails via SMTP from several other applications, so I am pretty sure it works correctly.

MT5, on the other hand, encounters problems.

When connecting via port 465, there is an "unknown error":

MailDispatcher    login to example.com:465 failed [unknown error]

When connecting via port 25, there is a mysterious "error code 220":

MailDispatcher    login to example.com failed [failed send data, server error code [220]]

As far as I know "220" isn't an error code, but a normal response from an SMTP server.

Unfortunately, I couldn't find any more detailed logs in MT5 to investigate this further.

Is there any method to make MT5 output more information about its connection to the SMTP server?

Did anyone encounter similar problem before?

I have some old ways about emails:

email-login:
https://www.mql5.com/en/forum/106329
https://www.youtube.com/watch?v=lSomE8aFa2Q
gmail: smtp.gmail.com:465; smtp.gmail.com:587; smtp.gmail.com:25; 100.100.100.8:25 => (use authentication); Use Authentication: Yes; Use STARTTLS: Yes (some clients call this SSL); Port: 465 or 587
GMX-Server: mail.gmx.com:587
Yaho-Server: smtp.mail.yahoo.com:465 || smtp.att.yahoo.com:25

It seems that GMX now judges the mails from mt5 as junk due to their simple structure which is often used by bots.

Hi Guys, So is that possible to use the SMTP from Google's servers? and if that is possible, could anyone kindly let me know how...

Thanks, but I already know how to set up email settings in MT5. I am encountering a specific problem and I hope to get some recommendations for solving it.

Apparently, this was solved by enabling plaintext authentication in the mail server's Exim.

Now, July 2022, I have similar problem with MT5 or MT4.

I have tried using gmail, yahoo, or paid smtp, but not one of them seems works.

first i thought that it because lesssecureapp on google no longer applied, so i tried with other email.

What about an email server on your pc? Google e.g. for hMailServer.

Email notifications work fine, check your email MT4/5 settings.

You go to MT4/5 >> Tools >> Options >> Email tab and you fill in the necessary details for your email and server, in order to receive your email notifications. Below is an example of the details that are required and a list of the most popular email providers and their SMTP settings.
