  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Resolved Problem with Plesk and Mailrelay, Mails gone

Regular Pleskian
Hi,
I have Problems with finding some Emails.
We are using SpamExperts to Filter Emails before origin Server.
The Log from SpamExperts for example are following after having conversation with Support:

Code:

2019-06-05 16:33:18 [116326] 1hYWyY-000UDu-20 Completed

after checking my Side, (I already checked Mailbox from Customer, theres NOTHING) I finally saw our Log:

Code:
Jun  5 16:33:18 hostname postfix/qmgr[13266]: 5105BC0711: from=<[email protected]>, size=188390, nrcpt=1 (queue active)
Jun  5 16:33:18 hostname postfix-local[16620]: postfix-local: from=bounces+1.148878-info=sendersdomain.de@emailus.freshdesk.com, [email protected], dirname=/var/qmail/mailnames

But i don't find the Email, it's not there. What am I missing?
I also ran things like this:

Code:
root@hostname:# doveadm search -u '[email protected]' HEADER Message-ID '5105BC0711'
root@hostname:#

Nothing.

Where can the Mail be?
MagicSpam is running on this Server, but the Domain from Customer "@mycustomer.com" is completely whitelisted in there.


System:
‪Debian 8.11‬
Plesk Onyx Version 17.8.11 Update #54
Postfix / dovecot

Additionally main.cf Settings:
Code:
/etc/postfix/main.cf

smtp_sasl_security_options = noanonymous,noplaintext
smtp_sasl_tls_security_options = noanonymous
smtpd_sasl_security_options = noanonymous,noplaintext
smtpd_sasl_tls_security_options = noanonymous
smtpd_tls_dh1024_param_file = /etc/postfix/dh_2048.pem
smtpd_tls_dh512_param_file = /etc/postfix/dh_512.pem
smtpd_tls_eecdh_grade = strong
tls_preempt_cipherlist = yes
smtpd_tls_loglevel = 1
smtp_tls_loglevel = 1

## SpamExperts
sender_dependent_relayhost_maps = hash:/etc/postfix/sender_relayhost
recipient_canonical_maps = tcp:127.0.0.1:12346
recipient_canonical_classes = envelope_recipient,header_recipient
authorized_flush_users =
authorized_mailq_users =

# RBL Override for Spamexperts inserted 2019
smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, check_client_access hash:/etc/postfix/rbl_override

Code:
# cat /etc/postfix/rbl_override
delivery.antispamcloud.com OK

EDIT: Maybe there's a Problem with SRS? If yes, what can i do?
Because normal Emails went through. But this complicated Freshdesk Mail was not found in Mailbox.
