Looks like your downstream server rejected the mail. PMG accepted the mail and then tried to deliver it to the downstream server which did not accept it.
Here PMG accepts it.
Code: 
Jun 29 13:02:44 mailgateway pmg-smtp-filter[1975]: 38136860DAEFC057CC4: accept mail to <ERKAN@xxxELEKTRONIK.NET> (36AB43814C6) (rule: default-accept)

Here you can see that PMG tries to deliver it to the downstream server, but it gets rejected by the downstream server.
Code: 
Jun 29 13:02:45 mailgateway postfix/smtp[2260]: 36AB43814C6: to=<ERKAN@xxxLEKTRONIK.NET>, relay=192.168.53.xxx[192.168.53.xxx]:25, delay=1.2, delays=0.05/0/0.01/1.1, dsn=5.7.1, status=bounced (host 192.168.53.xxx[192.168.53.xxx] said: 550 5.7.1 Message rejected as spam by Content Filtering. (in reply to end of DATA command))
 
Change your downstream server so that it doesn't bounce those emails.
According to the following log entry it isn't recognized as spam by PMG:
Jun 29 13:02:44 mailgateway pmg-smtp-filter[1975]: 38136860DAEFC057CC4: SA score=0/5 time=3.829 bayes=0.00 autolearn=no autolearn_force=no hits=AWL(0.764),BAYES_00(-1.9),DKIM_SIGNED(0.1),DKIM_VALID(-0.1),FORGED_SPF_HELO(1),KAM_DMARC_NONE(0.25),MSGID_FROM_MTA_HEADER(0.001),RCVD_IN_DNSWL_LOW(-0.7),RCVD_IN_MSPIKE_H2(-0.001),SPF_HELO_PASS(-0.001),SPF_NONE(0.001)

So maybe check to see what the 'Content Filtering' of your downstream server recognizes as spam in that mail.
