Email sending issue (was: URGENT)

[mmtrade]

@jdaviescoates this is 100% cloudrun issue

i changed servers just to be sure and i still have thesame error messsage assame as last VPS server

i tried connecting to telnet not working

this messed my email campaign up.. i also put it some triggers to make sure it does not come into spam and send emails at the rate off 200 per 30 mins.

see attached

the problem is from cloudron and you need to fix this. This is no server issue. Since you made your upgrade it has messed our servers up.Check this internally because this same issue cannot happen with a different VPS provider

@mmtrade Again, you’ll want to check the mail container status and logs, as that will likely be the most telling if the issue is in Cloudron or not. Maybe include a screenshot of the services list, and include a snippet of the latest log lines before and after restarting the mail container. That will probably be helpful.

[mmtrade]

@d19dotca can you tell me how to check this?

[d19dotca]

@mmtrade @jdaviescoates showed how to do that above. Go to Services page and click the log icon next to the mail line.

[mmtrade]

@d19dotca can you give me a SC on this

[mmtrade]

I mean can you give me Screeshots for this review? Do you think this problem can come from the OS?

[scooke]

Are you being purposefully obtuse and difficult @mmtrade? Several times you've been asked to check something by someone trying to help you, and you don't do it. You either reinstall the entire server or just ignore the posted help. You're wasting everyone's time if you won't follow the suggestions.

Something is off here.

@scooke thats not a nice thing to say... wasting someones time? I asked to give me directions to check this.

@d19dotca thanks for all your help but i actually want to check the logs part if i can get help with it

I tried reinstalling the whole thing and it will start working after some time this error will come up again

i have tried that several times

[mmtrade]

it is not fun coming to this review forum to keep talking about a particular problem. I have tried with 2 different server VPS and all give same result.

After some time they stop working. The first was the spamHouse now i actually do not know if it is the domain or what but am now sure it is not the service VPS provider.

I am trying to eliminate these issues one after the other for me to find the cause off the problem.

I really need help

I just tried accessing your domain my.miritz.bio but got a refused to connect error.
Also I can see that you only have an A records and no AAAA record:

dig A my.miritz.bio +short
213.232.235.195
dig AAAA my.miritz.bio +short

And your PTR is:

dig -x 213.232.235.195 +short
miritz.bio.

But I can't verify the AAAA PTR Record.

Using the bare domain as the mail server domain can lead to many issues like DNS propagation times.
But your choice.

At least the IMCP Ping is working:

ping my.miritz.bio

64 bytes from miritz.bio (213.232.235.195): icmp_seq=1 ttl=119 time=78.7 ms

Also I just run nmap -T Aggressive -A 213.232.235.195 also the following might be false but:

Windows? Maybe a Windows Virtualized Setup?

Your posted putty screenshots connecting to root@host are you really using a VPS and not a home server setup?

You were requested several times, by several different people to provide the mail service logs which you did not provide.

No. What you are doing is not very nice.
You have been given directions, yet you reinstall everything, so anyone who has spent anytime thinking about the problem as you stated has now had their time wasted because you didn't follow the steps they suggest. Now the situation has likely changed somewhat, so everyone has to start over with your poor description of the problem (other than it sure looks like you are a spammer... 5436 emails??? and 10k+, and that is the reason for your email troubles) As @BrutalBirdie points out, you have not yet provided the mail service logs, despite being asked for it, and having been given instructions about how to get them, as well as a screenshot showing you where to click to get them!!!!!!!!!!!!!!!!! Do not ask for that again... just read this entire thread and you will find them.

Not only requested, but descriptions and screenshots of exactly where to find those logs provided too.

[mmtrade]

@BrutalBirdie I told you that i have been trying to trouble shoot this myself. I have not left these domains untocuhed and i have been looking for a way to go about the whole situation.

However, I have replaced and changed IP's different times on my request to be sure that the problem is not coming from my side. That is called troubleshooting.

i will however re-install this server and see what will happen after this. I will keep you posted then we can work on the new IP.

It would help if you would actually read and acted on all helpful responses myself and others have provided.

We have already given you descriptions and screenshots of exactly where to find mail logs, but you still haven't shared them, and worse you come back asking for the exact instructions again as if we haven't already provided them.

Sorry, but I agree with @scooke: you are completely wasting everyone's time. Including your own.

[mmtrade]

@jdaviescoates please share the link for the screenshots again.

i did not receive them

[mmtrade]

@scooke i actually do not know your motive. i created this thread and i never pointed out to you had any direct question with you. I see you are seeking relevance. Please go out off my thread as i have serious people to engage with.

I will not answer you or respond to you anymore

Please do not take this negatively.
This proves that you are not reading or understanding the responses people write here.
He posted it here: https://forum.cloudron.io/post/104300 and you were not even able to scroll up and read but ask for the link.

Is there maybe a language barrier? I had other topics where we had to switch to french to resolve the issue efficiently.
If that is the case, please let us know.

Is this one of the first spam-AI-agents?
