Problem with the mail box

hello everyone I'm back here, I reinstalled following the guide suggested by Taleman to be able to make the mail work, now this happens when I send mail from my inbox it appears to be sent because it does not reach the recipient, instead when I try to send it from another mailbox to mine always gives me that damn error, "Reason: This is the mail system at host smtp-16.iol.local.I am sorry to have to inform you that your message could not be delivered to [email protected]. message is attached below. The remote mail system said: 554 5.7.1 <[email protected]>: Relay access denied "

Did you test sending from your inbox to the same address, with webmail? Then with an e-mail client? Have you followed the testing and troubleshooting instructions in the tutorial?
Using Internet Search Engines with the error message shows promising pages:

Code:

The remote mail system said: 554 5.7.1 <[email protected]>: Relay access denied "

Do this:
https://www.howtoforge.com/community/threads/please-read-before-posting.58408/
Reverse name service PTR record is not correct for e-mail server:

Code:

$ host incoming.webitalia.it
incoming.webitalia.it has address 80.83.161.2
tale@ika ~
$ host 80.83.161.2
2.161.83.80.in-addr.arpa domain name pointer incoming.media.it.

You could use e-mail server testing tools in the Internet instead of asking here. Like mxtoolbox.com or similar. Then when the tools find no errors, you can ask here if e-mails still do not work.

 

hello, I communicate with satisfaction that I have solved my problems with the mail, my problem was that I had not set an A record pointing from my provaider domain to my web server, thank you for your availability and sorry again for my incompetence .
