Issue Issue with Outgoing Spam-Mail

[Tim H.]

Hello guys!

I've been using Plesk for a few days, and it works great! However, the email function doesn't work. The problem is that POP3, IMAP & SMTP are not encrypted even though I have installed an SSL certificate. The emails go out, but they end up in the spam folder.

These are my Settings
DNS Settings:
SSL Certificate Settings of the Domain:

General SSL Certificate Settings:

My E-Mail Settings:

Message when I want to connect my E-Mail Account with Thunderbird:

Message when I click on connect with my E-Mail Account with Thunderbird:

And no the Domain isn't blacklisted. I tested it with multiple Domains.


I would be grateful if you could help me.

The "Configuration found at email provider" is bad. Go to "Manual config" and switch to SSL.
That is a thunderbird settings problem, not a plesk one.

Also, it has nothing to do with sent mails going into the spam folder.
That is another issue: You have activated DKIM.
For that to work, the domain keys must be accessible through DNS.
It seems you are using ovh.net's DNS servers for your domain(s).
In that case, you must copy the _domainkey, default._domainkey and _dmarc entries from https://<yourpleskdomain>:8443/smb/dns-zone/records-list/id/d:1 etc. to the ovh dns admin panel.
