I just checked your server from the outside and it accepted the recipient contact@locations-portovecchio.com:

# telnet locations-portovecchio.com 25
Trying 91.121.73.5...
Connected to locations-portovecchio.com.
Escape character is '^]'.
220 ns301169.ip-91-121-73.eu ESMTP Postfix (Debian/GNU)
helo xxxxxxxxxxxxxx
250 ns301169.ip-91-121-73.eu
mail from: <xxxxxxxxx>
250 2.1.0 Ok
rcpt to: <contact@locations-portovecchio.com>
250 2.1.5 Ok

So your server is able to receive mails for this address.

Some more stuff to check:
- Did you have problems sending mails or receiving mails?
- Which settings (servername, port) did you use to send mails?
- Which settings (servername, port, protocol) did you use to retrieve mails?
- Check your mail server logs for any hints

I can't send mail to gmail adresses. With another mail adresses it works...
I have seeing : Unable to send an email: Our system has detected that this message does not meet IPv6 sending guidelines regarding PTR records

But I'm not understan very well...

Please explain "can't send to gmail".
- Do you a non-delivery report? If so, what does it say?
- Do you get an error in your mail client when you try to send? If so, what does it say?
- What does your mail log file say?

Sorry, I have a non-delivery report :

The mail system



<frenchqwerty@gmail.com>: host

gmail-smtp-in.l.google.com[2a00:1450:400c:c07::1b] said: 550-5.7.1

[2001:41d0:1:7e05::] Our system has detected that this message does

550-5.7.1 not meet IPv6 sending guidelines regarding PTR records and

550-5.7.1 authentication. Please review 550-5.7.1

Bulk Senders Guidelines - Gmail Help for more information 550

5.7.1 . h144-v6si825663wme.116 - gsmtp (in reply to end of DATA command)

And there is the logs :

(Your log file does not show the part where the mail was sent to gmail)

But the error message is quite clear in the non-delivery report: Your server has no PTR for the IPv6 address 2001:41d0:1:7e05::, that's why Google rejected your mail.

Solution:
- Ask OVH to add a valid PTR for your IPv6 address
- Or disable IPv6 on your system (wouldn't do this, as IPv6 is the future anyway)

There is the log mail after send an email :


Ask OVH to add a valid PTR for mi IPv6 address ? The problem is not my mail configuration ?
