Ok remove it, probably restart the server, it should fix the unbound problem

Now, all looks good, I will check the email and let you know.
Michel-André
Thanks Andy, you’re right, I got carried away.
this message was not for you
excuse me
From webmail at Frederic, sending to my address:

mailbox table (in reply to RCPT TO command)
Still a little problem but it is different from the previous one.
Michel-André
root is a specific user I think, not sure it is reachable like this, use postmaster@fio01.com or admin@fio01.com if it exists
it is another problem that it needs to be found and different of unbound
Back to maillog when you want to send the email
It is getting a little bit better.
I can send an email from my server to fred and he receives it.
From fred, if I reply to the received email, it goes to the queue.
I wil check the logs.
Michel-André
Good evening and thank you, for your help of course.
stephdl, sorry I regret my outburst
Frederic

could you use the port 587, eventually with a smarthost just to test for while
fred can send himself a message, receives it, replies to it by transfer to himself and receives it OK
But I cannot sent to my address:
The mail system
<[michelandre@my.FDN](mailto:michelandre@my.FDN)>:
host mail.fio01.com[192.168.1.1] said: 554 5.4.0
Error: too many hops (in reply to end of DATA command)
Michel-André
P.S. Taking a break for lunch…
Taking a break for sleeping
Use a real smarthost, not a local account to relay, I suspect maybe a réputation issue.
Please other Time zone could you help
Thanks for your help, maybe it’s easier to reinstall everything.
I don’t understand. Everything was working 2 or 3 days ago, and I changed the IP 15 days ago.
Don’t waste your time with this,
Frederic
Maybe could help?
Salut Stéphane,
Andy made a smarthost.
It works perfectly: send and receive.
Michel-André
Hi all,

Probably a automated bot. Threat shield once they figure out an easy listing mechanism should be able to help mitigate these kind of attacks.
