How to outwit google or find the optimal solution?

Question

PHP

Good afternoon dear ones!
The essence of the problem is this:
Google has blocked letters from the site that are sent using the php-function mail ()
For example, the client places an order > an xlsx file is generated - headers - the body of the letter ... and sent to him.
Letters of the following type:

Delivered-To: [email protected]
Received: by 10.159.37.141 with SMTP id 13csp37884uaf;
        Wed, 10 Feb 2016 23:35:23 -0800 (PST)

Google support is "abandoned city". The forums on it, since 2013, have been filled with anger and pleas to unblock ip
Google's recommendations for mailing lists - I tried to do everything according to them, but the hoster does not support DKIM.
SPF - with the indication of ip ranges did not help. (maybe useless, since my knowledge is far from perfect and I did not fully understand)
I also wrote redirect - hc.ru and the entire ip range and exactly the ip through which it sends letters.
Server support, only reply "does not support", "impossible", use smpt send.
Now the actual question:
1. If you use not the php-function mail (), but SMTP, for example, with a connection to the mailbox [email protected], will this guarantee that Google will not ban again (because
2. Is it possible to do without editing the code and cure it with the correct spf entry and Dmark
Maybe someone has already come across ...

Answer 1

headings

List-Unsubscribe: [email protected]
Precedence: bulk

+ SMTP was always enough. Only with Yahoo sometimes problems.

Answer 2

Hello!
If the number of emails you send is not that high and you don't send spam, you can use the public smtp mail.ru for example. You also need to follow the rules of "legal" mailings in order not to fall under the filters.
If you send a lot of letters, then it may be worth using specialized providers (Unisender, MailChimp). But even this, with a large number of letters without DKIM, will not save you.
In the yard of 2016, now vpn is as shared, and you are still with a hoster that does not support DKIM.

Your envelope-from uses the default address [email protected] No SPF records published for fe122.hc.ru
>host -tTXT fe122.hc.ru
fe122.hc.ru has no TXT record
Previously, Google used the best guess record when checking SPF (in this case, the domain name matches the PTR record, so SPF was considered passed), but now it has abandoned this, because. this behavior is not consistent with SPF standards and violates DMARC policies.
Use your domain address

in the envelope-from and publish to your SPF domain.
