Email Error Using SMTP2Go

[Bruce1952]

Hi All,

Running version 1.58a on a linux server running PHP Version: 8.1.31

I am runing SMTP2Go through Microsoft Outlook and it is working how it should no issues.

These are the settings I have for emails.
1. Newsletter Modules: newsletters,product_notification,back_in_stock_notification,recover_cart_sales, addon_review_reminder

2. Email Transport Method: sendmail

3. Newsletter SMTP Email Mail Server Port: 80

4. Newsletter SMTP Email Mail Host: 45.79.238.223 (as suggested SMTP2Go)

I have attached part of the chat with SMTP2Go here also the error message is here:

Chat:
Rick from SMTP2GO: The basic SMTP settings do appear correct there.

Does it always get hung up if you try different ports?

The following SMTP ports are available:
TLS or no encryption >> available on ports 25, 2525, 8025, 587 and 80.
SSL >> available on ports 465, 8465 and 443.

12:30 AM | [email protected]: Yes it hangs on different ports but have only used a couple

12:33 AM | Rick from SMTP2GO: Can you please try further ports?

If it allows, you may be able to set an IP address instead of "mail.smtp2go.com". The IPs to try would be: 45.79.238.223 or 172.105.254.10

Any help would be appreciated as I don't know why it will not work.

Hi All,

Looks like it might have been smtp2Go server issue and now things seem to be working ok.

For future reference, "SMTP connect() failed" means that your Zen Cart store was unable to connect to the SMTP2Go server using the IP/port/hostname/username/etc configuration settings provided.
And, if it "suddenly just stopped" after "working fine previously", chances are very high that it was something malfunctioning on SMTP2Go's end.
