Hello there: First of all I apologize for the quality of the English text (Google Translate). I have an Ubuntu 20.04 installation following the instructions in (https://www.howtoforge.com/tutorial...sl-pureftpd-bind-postfix-doveot-and-ispconfig /), using ISPConfig 3.2.5. The server data is this: Code: ##### SERVER ##### IP-address (as per hostname): ***.***.***.*** [WARN] could not determine server's ip address by ifconfig [INFO] OS version is Ubuntu 20.04.3 LTS [INFO] uptime: 08:47:38 up 9 days, 38 min, 2 users, load average: 0.04, 0.03, 0.00 [INFO] memory: total used free shared buff/cache available Mem: 7.8Gi 1.9Gi 1.5Gi 17Mi 4.4Gi 5.6Gi Swap: 12Gi 0B 12Gi [INFO] systemd failed services status: UNIT LOAD ACTIVE SUB DESCRIPTION ● snap.lxd.activate.service loaded failed failed Service for snap application lxd.activate LOAD = Reflects whether the unit definition was properly loaded.

Reviewing the postfix configuration, I found the following detail: (double ',' example ", ,"): Code: smtpd_helo_restrictions = permit_mynetworks, check_helo_access regexp:/etc/postfix/helo_access, permit_sasl_authenticated, reject_invalid_helo_hostname, reject_non_fqdn_helo_hostname, check_helo_access regexp:/etc/postfix/blacklist_helo, ,reject_unknown_helo_hostname, permit Searching in the forum, I found the following entry in a thread : "Add sender address to postfix whitelist in ISPConfig Panel, EMail | Global Filters | Postfix Whitelist as type Sender.", in this case it would be to add "server.com". I followed the recommendation and the error disappeared. But being "server.com" one of the domains defined in "Mails / Domain" (as local) is it necessary to add in the white_lists? Thanking you in advance for your response. Sincerely.
This does not cause any problem. No, you normally don't need to add whitelist entries for your senders, just make sure they use authentication and send on port 587 or 465. Whitelist entries are only needed for unusual cases (eg. maybe a local machine/device on the network which you can't configure to send as your other clients normally do).
