Greetings hestiacp family, could you please help me with the following impasse that my email server presents:
I am using global SMTP Relay to send the messages, I am using the AWS/SES SMTP interface and it works fine, but I have not been able to receive emails in the Roundcube inbox, I have copied the DNS and the corresponding email domains configured to my server DNS (AWS/Route 53) such as:
I also have the ports open both in AWS/VPC-EC2 and in hestiacp:
I also exhaustively reviewed the blacklists to make sure that I was there and indeed I am not there.
Perfect example of why investigating the logs is relevant before posting to any forum.
The logs are clear:
Rejected because 126.96.36.199 is in a black list at zen.spamhaus.org
That needs to get fixed, either by removing the listing or removing the use of the blacklist.
The issue is that when I display the search for my IP and Domain in -SpamHaus- I get the following message:
172.31.92.94 (has no issues) however my mail server insists on blocking incoming messages, I already tried a replica server without SMPT Relay/SES redirection and the same thing happens, so we could rule out AWS/SES interference as Relay, I’m still researching and trying to find a solution. Surely you will have already noticed that I am not an expert in servers, even so I am not going to stop, neither with my project nor with the search for a solution, I appreciate your interest in this topic.
Its spanhaust PBL thats the issue, it blacklists every server that does not have a host that matches the rdns IP host name.
I contacted my ISP to pay to get this changed but they will not so emails to hotmail are blocked for my server i am affraid.
Most vps, dps allow you to change the host name of the ip address to overcome this issue like 123-reg does in the control panel.
It is a fearure thats good in one way because of the amount emails thy send you to scam sites we see everyday but on the other side if you want to host emails servers you need a feature from your vps dps or isp to change the ip address host name, the other more expensive option is to buy your own ip block but in this day and age excess capital is the issue plus alot of providers wont use your ipaddress block as they make extra income by selling you extra ip addresses.
The results of your research are really disturbing, however I will try to edit and change the hostname of the IP address on the VPS.
when I contacted my ISP I didn’t get encouraging answers either, so the possibilities and options are exhausted, I’ll put your recommendation into practice and come back with the results.
Thank you very much for contributing to this issue.
