Resolved all outgoing mails ends up in spam folder(gmail,outlook,etc..)

[ophiel]

first of all i'm almost a complete beginner at using plesk everything that i know comes from posts in this forum so sry in advances if i don't get it right away:
so i'm using plesk onyx 17.5.3 installed in an OVH vps equipped with "Ubuntu 16.04 server" . I've added webmail as a subdomain using RoundCube, so far it's working fine with ssl installed the only issue is that all outgoing mails ends up in spam folders be it gmail,outlook etc...
among the options that 've enabled :

• Tools and settings->mail server

1. DKIM spam protection->allow siging outgoing mail
2. Enable SMTP service on port 587 on all IP addresses
3. Outgoing mail mode->
   Send from domain IP addresses and use domain names in SMTP greeting

i'm more then happy to share any necessary information and thank you

Hi ophiel,

the theory is great, but when it comes to issues/errors/problems, you really should consider to provide the FQDN, so that people willing to help you have something to start with their investigations.

Recommended sites to test your settings on your own:

=> Network Tools: DNS,IP,Email
=> Newsletters spam test by mail-tester.com
=> DKIM Core Tools​

The "Outgoing mail mode->Send from domain IP addresses and use domain names in SMTP greeting" sometimes gets this behaviour on delivery...
I do prefer to sen all mail from just one ip address....

Thank you for the comment, but I'm afraid to tell you, that this statement is unproven and without any help, if you can't point to the root cause of your statement.
I can't confirm at all, that the setting "Send from domain IP addresses and use domain names in SMTP greeting" is able to cause the described issue at GMAIL, hotmail, outlook, or any other free - eMail - provider, in fact, it is rather the complete opposite, that such a setting will rather solve issues/errors/problems as described by the thread starter, but this presupposes, that the DNS - settings for the domain are setup correctly.
