[Solved] Request for rDNS

[tdm]

Hi !

I recently moved the registration mail function on my site to plesk using phpmailer and everything is going well, but... all sent mails go into receiver's spam folder, except for the gmail addresses.

I checked with mail-tester.com, it gives 10/10 but says that :

Your IP address 65.19.154.93 is associated with the domain name 3(NXDOMAIN).
However your message seems to be sent from tommy2.heliohost.org.

You should change the DNS pointer record (Type PTR) and the host name of your server to the same value

Here are the tested values for this check:

• IP: 65.19.154.93
• HELO: tommy2.heliohost.org
• rDNS: 3(NXDOMAIN)

 

This looks to me like Chinese stuff and is way beyond my skills !

I'm using two mail addresses (don't know if that matters) : 

• admin@tdm-yamaha.heliohost.org
• no_reply@tdm-yamaha.heliohost.org

Thanks for your help, I always appreciate the support found here.

An admin will need to change that record for you, as Plesk DNS zone permissions are not currently enabled for customer accounts. I am going to page @Krydos, @wolstech and @KazVee and they will get you sorted in a bit.

I do not offer a pager service.

DNS records are not something I can edit. 

All staff members are volunteers. You can read more about request ETAs here: https://wiki.helionet.org/hosting/repair-times 

I volunteer my time helping on the forum when I have free time and when it's fun for me to do so. 

Pinging me unnecessarily makes it not fun for me to spend my free time on the forum. Please don't do it again, thanks!

Oops sorry, about that, I did not know that. I assumed all staff had access to the user's website settings. I am just trying to volunteer my time as well.

Try it now.

Thanks, but now I got the Plesk def page instead of the site !

Additionally the back-office pages are no more https.

 

Web Server's Default Page

This page is generated by Plesk, the leading hosting automation software.
You see this page because there is no Web site at this address.

I flushed the cache and site is ok now.

No more rDNS issue with mail-tester but now ALL mails go inside spam boxes - tested on yahoo.com / outlook.com / free.fr /gmail.com. :-(

gmail worked ok before !

Noted:

Weight of the HTML version of your message: 26KB.

Your message contains 3% of text.

Try using a greater text-to-HTML ratio or ditching HTML email messages altogether as that tends to cause problems.

Thanks !

It also looks like   

$smtp->Encoding      = "base64"; 

in my code is wrong as "base64-encoded HTML bodies make you look like a spammer" (from stackoverflow.com)

So I changed it to 

$smtp->Encoding      = "quoted-printable";

Now the problem is I cannot test this due to the "SMTP quota exceded" error !

Is it possible to have a temporary quota limit above 10/hour ?

 

[tdm]

So, things are ok now for both html and text body when using

$smtp->Encoding      = "quoted-printable";

The issue remains with outlook.com event when sending plain text (utf-8) mails, they all go to the spam box.

According to github.com there is nothing I can do : https://github.com/PHPMailer/PHPMailer/issues/1412

The more important is that it is ok with gmail.com and yahoo.com for html body mails.

Hope this helps.

Thanks Team for your support !

Yeah, we can set it to 50 per hour, but you're still limited to 50 emails per day, and if you exceed the 50 limit your email sending privileges get revoked entirely so the 10 per hour limit helps people from getting disabled entirely. If you need to send more than 50 emails per day the limit can be raised, but we need additional information from you first.

[tdm]

Thanks but no need for a quota raise, I've sorted the issue.

Actually my site sends emails only for user's registration &  when they forget their password. So that's no more than 10/day.

The quota limit raise was only required when trying to sort the problem of mails ending into spam boxes and therefore having to use phpmailer more than usual for testing purposes.

My site does not use any cms, I've coded all php/mysql/javascript by myself.  You may ask more info if you need to.

Thanks again for the help.
