Siehe meine andere Mail, auf dem Server selbst läuft wahrscheinlich
auch noch eine iptables Firewall. <br>

Ist dies nur für den Testfall, sonst ist das viel zu wenig. Üblich
ist mehrere Tage.<br>
Du kannst "delay_warning_time = 60" nutzen, um eine Benachrichtigung
an den Absender zu schicken, wenn in 60 Minuten die Mail nicht
ausgeliefert werden konnte.<br>
Ebenso confirm_delay_cleared, um nach erfolgter Zustellung eine
Aufhebung der Verzögerungsmail zu schicken. <br>

Meine Empfehlung wäre statt "accept" ein "tempfail", sonst hast Du
eventuell das Problem, dass bei kaputter rspamd-Konfiguration der

<br>
Hier wird es interessant: Du hast Domains in <br>
- mydestination (local Domains, die gültigen Empfänger sind in
local_recipient_maps)<br>
- relay_domains (gültige Empfänger in relay_recipient_maps)<br>
- virtual_mailbox_domains ( gültige Empfänger in
virtual_mailbox_maps)<br>
Prüfe am besten, ob wirklich überall die Domains dort richtig sind.
Wahrscheinlich sind die Domains in mydestination und relay_domains
besser alle in virtual_mailbox_domains aufgehoben.<br>
<br>
Prüfe bitte auch, ob auch alle notwendigen Pakete installiert sind.
Damit Postfix über cidr, regexp, mysql, ldap etc. auf Maps zugreifen
kann, müssen oft Pakete installiert sein, welche diese
Funktionalität mitbringen. <br>
"postconf -m" zeigt, welche Maptypen Postfix beherrscht. Bei mir auf
Centos etwa ist kein mysql in der Standardkonfiguration enthalten.<br>
postconf -m<br>
btree<br>
cidr<br>
environ<br>
fail<br>
hash<br>
inline<br>
internal<br>
memcache<br>
nis<br>
pcre<br>
pipemap<br>
proxy<br>
randmap<br>
regexp<br>
socketmap<br>
static<br>
tcp<br>
texthash<br>
unionmap<br>
unix<br>
<br>
ich müsste dafür das Paket postfix-mysql installieren, damit ich
mysql-Abfragen nutzen kann.<br>
Auch für pcre und cidre müssen oft Pakete hinzuinstalliert werden.<br>

Wenn "postconf -m" zeigt, dass mysql als maptype existiert kannst Du
prüfen, ob die Abfragen denn auch ein Ergebnis bringen.<br>
"postmap -q 'was-du-suchst'
mysql:/etc/postfix/sql/mysql_virtual_sender_acl.cf"<br>
<br>
Schaue Dir bitte auch die Liste der proxy_read_maps an, da werden
Sachen aufgeführt, die in Deiner Konfig nicht mehr verwendet werden
wie virtual_alias_domains, sender_canonical_maps, relocated_maps
usw. <br>
Schau Dir auch immer an, was der Defaulteintrag für diesen Parameter
ist, denn was Du in Deiner Konfig nicht explizit verwendest
(postconf -n zeigt dies) wird mit dem Default hinzugenommen. <br>
<br>
postconf -d transport_maps<br>
transport_maps =<br>
<br>
Der Default bei mir wäre z.B. eine leere transport_maps, was diese
Tabelle abschaltet.<br>

Du hast wahrscheinlich eine Firewall auf dem Server selbst aktiv,
welche die Verbindung zu Port 25 blockt. <br>
Da sind noch einige Sachen strubbelig. Am besten, am Anfang führt
man eine Anleitung genau durch und bekommt dann ein funktionierendes
System (hoffentlich). Abweichungen kann man dann danach einführen. <br>
Bist Du nach dieser Anleitung vorgegangen:
<a class="moz-txt-link-freetext" href="https://thomas-leister.de/mailserver-debian-buster/">https://thomas-leister.de/mailserver-debian-buster/</a> oder was hast Du
als Vorlage verwendet?<br>
