Hi, for a good while (more then a month) im trying to get my vps machine(Ubuntu 16.04) ready for postfix to sent mails. Im using Plesk on it. But no matter how i configure my postfix my mails never wont get through spamfilter on several providers like gmail microsoft yahoo... everytime they end up in spam. I have more domains in my Plesk panel. I have one domain where i created a subdomain "vps.example.it" this is my server hostname (FQDN-SERVER-HOSTNAME) and this im using for the delivery of mails (Reverse PTR is set to this). The mx entry is also "vps.example.it". My server hostname = mailserver is because i only have a single IP, this way i use vps.example.it for ingoing also for outgoing. example.it is named on all code and logs "domain1111" the second domain "domain2222". So i provided a lot of stuff, trying to send a mail from my mail "[email protected]" to my gmail mail: Mail log vom Server: Code: Mar 26 10:42:13 vps postfix/smtpd[14762]: connect from host1-90-static.xxxx.business.telecomitalia.it[INTERNET-IP] Mar 26 10:42:13 vps postfix/smtpd[14762]: 69337860507: client=host1-90-static.xxxx.business.telecomitalia.it[INTERNET-IP], sasl_method=PLAIN, [email protected] Mar 26 10:42:13 vps greylisting filter[14764]: Starting greylisting filter...

The mail server is secured with the "vps.domain1111" certificat. In attachment you can find also a mail-tester.com result with 10/10, dns configuration, plesk email settings, header mail comparison from sending mail: left: yahoo.com -> gmail.com right: mail from domain2222 -> gmail.com, proof for setting right reverse dns. Im not listet in any Blacklist, checked a lot of tools and checked domain health, smtp diagnostics with mxtoolbox.com, dns stuff ... im passing everywhere. I listet my domains hostname there: postmaster google site I joined the jmrp and snds program on microsoft. I asked there: https://support.microsoft.com/en-us...rt_1.0.0.0&wfname=capsub&productkey=edfsmsbl3 https://help.yahoo.com/l/us/yahoo/mail/postmaster/bulkv2.html https://support.google.com/mail/contact/msgdelivery From microsoft support i recieved: We have completed reviewing the IP(s) you submitted. The following table contains the results of our investigation. Not qualified for mitigation 173.xxx.xxx.xxx Our investigation has determined that the above IP(s) do not qualify for mitigation. Edit: Shortly i included clamav antivirus check and is working: X-Virus-Scanned: clamav-milter 0.99.4 at vps X-Virus-Status: Clean Edit2: At the moment im using for mydestination and myorigin the (fqdn-server-hostname) vps.domain1111. I really don't know how to fix this problem and im really exhausted after so many days of failure .
