The action at the stage "sending notification by email" does not work

Good afternoon. In the integration settings, for mailboxes through which mail is sent, I recommend enabling the setting "Do not send emails from this mail if SMTP is not available" https://i.imgur.com/4Gr5c0P.png If this setting is enabled, if, for some reason, the SMTP server is unavailable the system will not try to send a letter using the mail method. With the mail method, errors are never returned, and letters end up in spam, or are generally rejected by the server. If you look at the log of sent messages for today, https://crm.ohholding.com.ua/admin/logs/showall/ajax/?file=sendmail-2021-01-26.log then you can see that the part was sent by method [5] => method: smtp and part method [5] => method: mail This indicates that the mail server does not always respond and the system is trying to send the letter at least somehow. Now the minute cron is connected to the mail server and the connection is established (ESTABLISHED) but nothing happens. php 2190243 testcrmohholdin 6u IPv4 969667536 0t0 TCP test-crm.ohholding.com.ua:49016->mail.ohholding.com.ua:urd (ESTABLISHED) Resolve issues with the mail server and the system will work.

Attached is the script that our admin wrote and ran on the server where the vanbox is located. This script sends a message to the mail.

For some reason I can't send the attachment. Can you provide an email address where I can send the file?

I don't know what your admin sends with his script. You asked about our product, I answered you what is happening. Gave a log where to look.

1. checking https://prnt.sc/xpjk88 from my event, a letter was sent to the admin's mail - I called him, he said that he had not received the message. At the same time, nothing was recorded in the logs at all, not even an error 2 check https://crm.ohholding.com.ua/admin/customorder/project/321266/edit/ created a test process, below you can see that vanbox sent a letter to the mail by actions, but in fact, these employees did not receive anything
