Resolved Problem with Plesk and Mailrelay, Mails gone

daanse

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 16:33:14 [116182] 1hYWyY-000UDu-20 DKIM: d=freshdesk.com s=fdusmail c=simple/relaxed a=rsa-sha256 b=2048 t=1559745194 l=184110 [verification succeeded]

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.
