Email sending issue (was: URGENT)

[mmtrade]

I have configured everything and started to use it normally. After some time the domain is red meaning that it is not configured or something has blocked it somewhere.

Please find attached for your perusal.

I actually have troubleshooted it but no update.

Please check if this is from the Provider or is it cloudrun blocking it?

@mmtrade that doesn't really tell anyone enough to be able to help. Click on miritz.bio and then on the Status tab and you'll see something like this (but something will be red):

Without more info it's impossible to be sure what the issue is. Saying that, it's quite likely something to do with IPv6, probably your PTR6/ rDNS/ reverse DNS record.

If it is that, see e.g. https://forum.cloudron.io/topic/13072/gmail-ipv6-anyone-else-with-this-experience/22?_=1742803464552

Yes see attached below

[mmtrade]

I cannot send or receive emails but at some point i was actually...

[mmtrade]

when i try to testrun an email see what it shows as attached

[mmtrade]

the thing is that it is red while it supposed to be green is where the problem is coming from

can you check and see whats going on?

[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

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