Email sending issue (was: URGENT)

[mmtrade]

I have had my IP's blacklisted and it does not affect the mail server

I am not able to unblock it if i cannot send or receive emails.

Most off these spam list sites will not accept email from a thrid party account

[mmtrade]

How do i debug this and remove this to start working

[Gengar]

@mmtrade On my side it's my fault. It's because this morning I changed the Unbound config by adding a forward.conf to use cloudflare dns... and spamhaus doesn't like that...

I will have to find a way to deal with that...

[mmtrade]

@jdaviescoates i have unlisted spamhouse and it is still thesame thing

when did this start? I have been using cloudrun for sometime and this issue has not come up

[mmtrade]

Now @jdaviescoates everything is okay but i cannot send or receive emails

see attached

also see attahced whem sending emails

Please go to https://my.DOMAIN.TLD/#/services and check if the mail service is running.
And if so, maybe restart it once and then send the logs of that service.

If the mail service is not running and can not be started, there might be a program like postfix running on your server which is blocking the ports.

[scooke]

Sounds like it is server-side. Has your vps provider done upgrades or changes lately?

[mmtrade]

@BrutalBirdie Please see attached if everything is okay

I have restarted the server and it is still not working

[mmtrade]

I still have thesame problem and the mail is working from what i can see here

[mmtrade]

See what the error message but it is not blacklisted on spamhouse

when did all these measures start because I never experienced with cloudrun before

[mmtrade]

[mmtrade]

when i try to test sending why does it show me another IP???

[nebulon]

Here it would connect locally, trying to send out a mail via the local mail service. Is your mail service running?

[mmtrade]

it is not connecting.. i tried using thrid party services but it does not connect

[nebulon]

What is not connecting where? I was only referring to the test email sending, to clarify why in this case you are seeing a local IP address.

[mmtrade]

@nebulon Well that is what i do not understand whats going on??

How can I rectify this?

Everything is okay but the mail is not sending or receiving. This has nothing to do with my service provider.

In a post on an originally unrelated thread about IPv6 issues @Gengar posted this link https://www.spamhaus.com/resource-center/successfully-accessing-spamhauss-free-block-lists-using-a-public-dns/ which I think explains what's going on with all these false positive spamhaus issues people are having:

@mmtrade are you able to connect to your mails service, if you run telnet via SSH on your server?

telnet 172.18.30.4 2525

When you say it isn’t sending or receiving… what happens when you try to send email exactly? And for receiving… are the senders getting a bounce back message? If yes, what does the bounce back say?

When you try to send… are you getting an automated error response back? Is your mail client showing a failure to connect to the SMTP server?

We need more information for anyone to help.

Are you certain your DNS records show the correct IP of your server for mail.{your domain.tld} and was that changed recently at all?

Is it possible your IP address is intermittently being blocklisted where it is showing listed and then later on is showing fine, and keeps flip flopping like that perhaps? The blocklist alert in Cloudron has no bearing on your actual mail functionality, it especially won’t have anything to do with receiving mail from others. If on a blocklist it still won’t impact your ability to send unless the receiving end is blocking it due to being on the blocklist, or may be delivered but found in spam boxes instead.

@mmtrade @nebulon @d19dotca

I deleted my whole server and started the reinstallation process again with a different host. Now it started working and sending mails. When i started my campaign, I noticed i could not send up to 1000 emails before this issue started again. I am being blocked and my emails will not receive or send. when i try to do a test it does not work and it still keeps showing me the attached. Everything just worked fine when i started the process again but i do not know why after some time i am being blocked....

Please i need answers to this urgently because I am loosing my mind.

I bet you if i start it all over again it will work and after some time it will stop working

whats going on and is this a new update with cloudrun

i have contacted VPS server provider and actually they do not block or alter any ports so this has to be a cloudron issue. If so why would it work then later stop

Is there any restrictions with this new upgraded cloudron??? the other versions never did this before. It was easy and fun
