Hello,

I am trying to upgrade from iRedMail 0.9.7 (using Ubuntu 18.04 Server) to 1.3.2 (using Ubuntu 20.04 Server).

The installation process is correct, and the restore of vmail and LDAP is also correct. In order to update LDAP y execute the script https://github.com/iredmail/iRedMail/bl … cot-2.3.py

When I try to send a mail y get "SMTP Error (451): Failed to add recipient "<user>@<domain>" (4.3.0 <<user>@<domain>>: Temporary lookup failure).".

Some logs appears at /var/log/maillog telling that:

Dovecot logs tells:

Dec 28 11:26:12 mail dovecot: master: Dovecot v2.3.7.2 (3c910f64b) starting up for imap, sieve, lmtp (core dumps disabled)
Dec 28 11:26:23 mail dovecot: stats: Error: conn stats-reader (127.0.0.1:41864): didn't reply with a valid VERSION line: EXPORT#011global
Dec 28 11:26:23 mail dovecot: stats: Error: conn stats-reader (127.0.0.1:41866): didn't reply with a valid VERSION line: EXPORT#011global

I know there are many releases to update at once, but the installer don't let me install older versions.

Thanks in advance and thanks for this awesome project.
