Hello,
I have an issue with Postfix after a new OS installation (64bits instead
of 32bits).
OS : raspi-os (Debian for Raspberry Pi, my mailserver run on a Raspberry Pi)
What I've done:
- OS 64bits installation
- Softwares installation (Dovecot, Postfix, Clamav, Spamassassin,
OpenDKIM, SPF)
- Put all old softwares files to new softwares (configuration and
others) because softwares version have not changed
==> No modifications made
Mailserver hostname and IP have not changed, exactly the same.
No firewall on mailserver (stopped because I have a strange issue with it).
The issue:
- When I send an email as root or others users, just for testing, from
another Raspberry server using commands line (echo "TEST" | mailx -r
"no-re...@mehl-family.fr" -s "TEST" for...@mehl-family.fr) I see these 2
messages in maillog on sending server:
*/postfix/smtp[23430]: 4972423BAF: to=/**/,
relay=192.168.1.160[192.168.1.160]:25, delay=0.99,
delays=0.06/0.03/0.8/0.1, dsn=5.7.1, status=bounced (host

and
/*postfix/smtp[23430]: 401F723BB0: to=*//*,

5.1.1*//**//*: Recipient address rejected: User unknown in virtual
mailbox table (in reply to RCPT TO command))*/
==> But I don't see any message in mailserver maillog.
- When I send an email from an external email (as Gmail) I don't receive
email and no message in mailserver maillog.
BUT...
- When I send an email using the same commands line from the same server
but with old mailserver OS (32bits), with exactly the same configuration
for all (Dovecot, etc...), I receive the email fine and I can see
message in mailserver maillog.
I search in all directions but I don't understand why it doesn't work.
HAPPY NEW YEAR !!!
