All messages bouncing except those to domain addresses

phplist version 3.6.15

Hello. Phplist had been working great for me until the beginning of July and then suddenly every message sent started getting bounced. I’ve run some test campaigns, and emails sent to addresses within my domain (drumbrothers.com) are getting through fine (listbounces@drumbrothers.com & grooves@drumbrothers.com). But emails to my other addresses at yahoo.com, gmail.com, and blackfoot.net which have drumbrothers.com whitelisted are still bouncing. Any ideas to the cause of this issue?
I’ve contacted bluehost to see if it’s a hosting issue and they haven’t offered any viable solution.

In my statistics overview it said that the 5 emails to my test addresses went through and there were no bounces even though I can see the bounces in listbounces@drumbrothers.com.

In my events log, it says that all the messages are being sent.

And here is an example of the auto-generated message for one of the bounces:
" This message was created automatically by mail delivery software.

Thank you for any help you can offer.

Best,

Matthew

I would suggest sending the message to a gmail address then viewing source. It will show you whether you have the SPF, DMARC and DKIM authentication systems set correctly. They are all set using a combination of DNS and embedded codes. There is even a DKIM plugin you can add to phpList.

Good Luck,
Doug

It looks like your IP address may be on a blacklist. I don’t know whether cloudfilter.net is rejecting the emails, or whether cloudfilter.net is the actual problem. Your hosting company should be able to explain what the role of cloudfilter.net is.

Thank you so much for your reply. Would you mind taking a look at the source of this bounced email to drumbros@gmail.com? This is dipping a bit deeper than my knowledge base, but I’m a good learner:-).

Thank you for the reply. I’ll ask bluehost about cloudfilter.net.
If my IP address is on a blacklist, are there steps I can take to remedy the situation? I only have about 2500 total members of the list and I message all of them around once a month. I do have a number of smaller subscriber lists of music students that I send class materials to (links to charts & mp3s, usually accompanied by a photo).

Best,

Matthew

Actually, if you are comfortable doing so, add my gmail address to your list and send it to me. Only by viewing the original message can I check the DMARC, DKIM and SPF settings.

My gmail is: DDougster AT gmail.com … yup, I did that on purpose to hide it from the address scrapers.

Thanks,
Doug

I’d be happy to. To be clear, if the message bounces to you, you’d like me to send you the source of the bounced email (titled~ Mail delivery failed: returning message to sender) received at listbounces AT drumbrothers.com?

M

No, I’m hoping to see the original message get to me. The bounce just says it bounced. The original outbound message is what I need. Have you tried setting up your SPF and DMARC to at least get some messages moving through? I had this same issue when moving to a new cloud provider for our web servers.

Doug

How about you email me directly at my gmail account. We can get connected via phone and get this thing resolved much faster.

Thanks,
Doug

@mtmatthew You do need to raise this problem with your hosting company, presumably bluehost.com because a range of IP addresses are on a blacklist
see https://www.uceprotect.net/en/rblcheck.php?ipr=162.241.252.173 then click the “Start Testing” button. The result shows that a range of IP addresses including your server’s IP address is blocked.

Here’s what I just heard from bluehost:
“You have Shared hosting plan. While checking this, I found that your shared IP address has been blacklisted in an external mail server, that’s in UCEPROTECTL3 - 'http://www.uceprotect.net/ '. Your server IP being blacklisting should have no effect on sending email through our email server and doesn’t effect website functionality.
Shared servers have shared IPs that are shared by multiple user accounts hosted on the same server, due to the mass amount of email that comes out of our shared servers, one of these IPs will inevitably become blacklisted. Unfortunately we are unable to request delisting of our shared IPs, it will de-list from the external mail servers eventually.
We are only able request delisting if our proxy IPs are blacklisted as we use proxy IPs to send out email to prevent blacklisting. The shared accounts use “Rotating Proxy IPs” to send out email to prevent blacklisting by providers. There are times that certain Proxy IPs will be blacklisted. When this happens our admins work on requesting them to be removed.”
and
“I am really sorry you are going through this. admins are working on this once its resolved admins will mail”
Thoughts?

UCEprotect will offer to “keep your IP off their list” for the right price. Our Domain is always listed on their servers as “spam”. However, since the DKIM, DMARC and SPF records comply, our mail almost always gets through just fine.

Doug

I’d suggest visiting MXtoolbox.com and setting up a free account. Then you can review blacklists by entering your domain name and seeing which have you listed. (Seriously, nobody takes UCEprotect serious so it’s not a problem).

Hope that helps,
Doug

Dougster was so gracious to help me fix the sending problem.

I have one more issue that you likely can help me with. Even though I have html selected in the campaign, the test recipients confirmed to receive html emails, have my config file set to define(‘SEND_ONE_TESTMAIL’, 0);, and can see the ckeditor just fine, both test emails are coming through as text only.

Could you point me in the right direction for a solution?

Thank you so much!
