Can't connect with SMTP

[shopglobal]

I'm trying to connect with SMTP and I'm not able to use the provided details in the configuration. Please advise, how have you been able to successfully send via SMTP? What's the process?

I've tried the following;

u/user
passKey

postal.mydomain.com
25 or 2525

[shopglobal]

When I add additional credentials how do I use then?

[shopglobal]

@willpower232 We have sent test messages successfully but not though SMTP

[willpower232]

You can try using postal status and netstat -lnp to see if you have an SMTP process for postal.

After you have created a credential, a link appears saying Read more about sending outgoing e-mails which tells you how to use the credential. Additional credentials are essentially different passwords for the same username.

[shopglobal]

I have followed the instructions on the help guide you've directed me to. Haven't been able to connect with SMTP yet. Server operational. What could I be doing wrong? Can you walk me through an example? Thank you for helping me to understand the credentials, once we get the default SMTP settings working we can use your advice to use different credentials.

Can you send the output of netstat -lnp from the terminal on your server? You will need to use sudo or be root.

[willpower232]

It might be worth verifying that the SMTP port is reachable.

Can you try using telnet from your computer to try to connect to your server? telnet postal.yourserver.com 25

P.S. screenshots are better than textual messages

[willpower232]

Thanks for that, have you had a go with telnet yet?

Can you try using telnet from your computer to try to connect to your server? telnet postal.yourserver.com 25

[shopglobal]

Yes able to connect and AUTH LOGIN with base64 encoded username and password. However SMTP doesn't allow me to connect from third party platform, so when attempting to authenticate from my delivery platform I still cannot authenticate...

Telnet suggests SMTP is working, and connection is authenticated with the credentials encoded in base64, however to note .. ... .... the SMTP connection between third party delivery platforms is still showing me errors. So when attempting to connect SMTP I am not authenticating from other platforms.

Should the Username and Password be encoded in base64 on the third party delivery platform? Should I be connecting with STARTTLS, or other methods? What is preventing the SMTP from connecting to third party delivery platforms?(seeing as Telnet method is working..)

I am only able to deliver any messages with clicking through messages/send test at postal.mydomain.com/org/v/servers/postal/messages/new
Verified receipt of tests, and all is working. But cannot connect to SMTP with my email delivery platform.. What am I missing?

As far as I am aware, you don't need to base64 encode things.

We had some issues with port 25 on AWS so used iptables on our postal server to create a second port to bypass any filtering. Have a go with #212 (comment)

[shopglobal]

I was able to start the SMTP server, and still not able to authenticate with my email platform.

Hello,
this is a test. Testing the SMTP on Postal.
.
530 From/Sender name is not valid

@willpower232 @adamcooke Note that "postal status" response does not list port #'s for active processes, if this is any indication of misconfiguration please let me know what to do. I am just not able to authenticate with third party delivery platforms using SMTP method as of yet. I have credentials, and verified telnet ability, but the delivery and authentication from other platforms is just giving me troubles. Hoping this can help

Postal status wouldn't be intended to show the ports since netstat does a much better job.

In the smtp section of postal.yml try putting the domain name for the host instead of any IP address.

'From/Sender name is not valid' implies that your domain may not be verified for the credential used so you should also check that.

[shopglobal]

That's how I have it setup. And the domain is verified. It's the same used in the telnet posted earlier.

Also can't send with API but testing works

Make sure you are using a credential that comes from the same area as the domain name you are trying to send with.

[Reklen]

Same issue it works with telnet command line but it doesn't work using another third party app such as spree mail setting https://github.com/spree-contrib/spree_mail_settings.
ps: I used credentials generated by postal
