OK if I use the -r, the from is OK
@alento : I sent you 2 tests email.
Yes I installed postfix as in this guide https://mailinabox.email/advanced-configuration.html
you I leave the default config, and jsut add the 7 lines ?
or empty the default config file and just have the 7 lines in it ?
I have my other mail at neomaibox service. it seem s they are delaying mail coming for my box :
Aug 23 15:57:39 nuage postfix/smtp: 8011717C4D3: Server certificate not verified
Aug 23 15:57:39 nuage postfix/smtp: server certificate verification failed for mail2.neomailbox.net[184.108.40.206]:25: certificate has expired
Aug 23 15:57:39 nuage postfix/smtp: 8011717C4D3: to=<email@example.com>, relay=mail2.neomailbox.net[220.127.116.11]:25, delay=80198, delays=80197/0.03/1.2/0, dsn=4.7.5, status=deferred (Server certificate not trusted)
and to a gmail adress , it seem to be the same ?
relay=gmail-smtp-in.l.google.com[18.104.22.168]:25, delay=0.67, delays=0.01/0/0.4/0.25, dsn=2.0.0, status=sent (250 2.0.0 OK DMARC:Quarantine 1566568488 x14si2118454wmj.156 - gsmtp)
In one of the test email, the log sent me to this link : http://postgrey.schweikert.ch/help/
but not anymore …
Mail sent to the gmail adress are marked as spam, how can I solve that ?
DNNSEC is activated for this domain…
I guess it is not related to relaying anymore, let me know if you prefer me to open an another topic
Thank you for your help !!!
