Two step verification

If you have two-step verification enabled for your Gmail account, then you'll need to create an app password. This is a 16-digit password that you will need to specify in the program settings. It's easy to create a password by following these Google instructions.

All errors when working with mail - analysis of the causes and methods of how to eliminate them.

The described errors are relevant for the SMTP sending method.

All errors that may occur when sending mail

Error: Email to required
Error: Email from required
Error: Email sender required
Error: Email subject required
Error: Email message required
Error: EHLO not accepted from server
Error: STARTTLS not accepted from server
Error: AUTH LOGIN not accepted from server
Error: Username not accepted from server
Error: Password not accepted from server
Error: HELO not accepted from server
Error: MAIL FROM not accepted from server

Error: E-Mail to required - the error will be when there is no data where to send the letter, simply, either mail is not configured in the admin panel, or the form does not transfer data to the library for sending.

Error: E-Mail from required - an error occurs when trying to send mail, but did not specify from which address to send. This may be due to the fact that either the mail was not specified, but there is no validation, or the store is not configured correctly.

Error: E-Mail sender required - everything is simple, it is not specified from whom the sending is. Not to be confused with email from. Just from whom it is displayed in the mail, either the person's mail or his name goes here.

Error: E-Mail message required - empty email.

Error: EHLO not accepted from server - this error occurs when the mail server settings are incorrect. Often you just need to specify ssl:// or tls:// in front of the mail server - this translates the sending of mail using a secure protocol. You must also specify port 465 otherwise this error will occur. These settings are in the admin panel in the settings - mail tab.

Error: STARTTLS not accepted from server - tls connection error. In this case, you need to look at the settings and find out which port and settings are needed to work correctly through tls on the mail server.

Error: AUTH LOGIN not accepted from server - invalid login. See mail and mail server settings.

Error: Username not accepted from server - Invalid user name.

Error: Password not accepted from server - the error may be due to either an incorrect password or non-existent mail. This is often due to the fact that mail has not yet been created on the server and we are trying to send a letter, or the password must be checked with a login.

Error: HELO not accepted from server - some hostings block work using the secure ssl mail protocol, so you either need to unblock it or go to port 25 without ssl:// or tls:// at the beginning of the smtp server

Error: MAIL FROM not accepted from server - an error that occurs when sending mail from the feedback form.
