Email sending issue (was: URGENT)

[jdaviescoates]

@mmtrade it's red because it thinks your IP is on a Spam blocklist.

Could very likely be the same as

That's funny @mmtrade because I'm having the exact same issue since today. And I had a look on https://www.spamhaus.org/ and it seems to be a false positive. My IP isn't black listed on their side.

[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:

[nebulon]

@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
