Describe your issue

I haven’t been receiving email, even from my install.
From my connected client, I can’t send email. When testing I receive the following message: The server response was: email@mydomain.tld: Temporary lookup failure

From Yunohost Admin Diagnosis, Email Section:

The SMTP mail server is able to send emails (outgoing port 25 is not blocked).
The SMTP mail server is reachable from the outside and therefore is able to receive emails!
Your reverse DNS is correctly configured!
The IPs and domains used by this server do not appear to be blacklisted
32 pending emails in the mail queues

Bon, en cherchant cette ligne je suis tombé sur ceci Impossible d'envoyer ou de recevoir des e-mail - #8 by jershon qui propose quelques pistes…

Done this, the client is now fetching mail. Not sure if the mail changes were listed in the update notes.

Just came here to link this with this thread..
I had the same issue, bcs I seem to have manually edited /etc/postfix/main.cf

So yunohost tools regen-conf -n -d returned:

...
-virtual_mailbox_domains = ldap:/etc/postfix/ldap-domains.cf
+virtual_mailbox_domains = /etc/postfix/virtual-mailbox-domains
...

I changed that manually and it is up and running again.
