    Hello everyone!
    Perfect server installed on Debian 10 running ISPC version 3.2.1 with Dovecot

    FQDN: adolf.schwimserver3.com
    RDNS: adolf.schwimserver3.com
    Email domain: adolf.schwimserver3.com
    Email address: [email protected]3.com set up domain and address via ISPC.
    ISPC / System / Firewall shows following TCP ports open: 20,21,22,25,53,80,110,143,443,465,587,993,995,3306,8080,8081,10000

    SPF, dmarc and mx records:

    Sending mail to address from outside mail(GMail) results in no mail in mailbox, mail.log only shows:
    Sending mail from the roundcube install to GMail account results in stalled page load in roundcube and the mail never arriving to the gmail account then shows the following in mail.log:
    mail.info:
    Everything just times out, both when trying to make it's way out and in. What am I dealing with? What am I missing in setting up usable email on my server?

    ISPC test script results:

    Did you change the master.cf according to the perfect server guide? It seems like you didn't.

    By the way, ISPConfig 3.2.1 and older have a security issue, you should update to 3.2.2.

    I did try to follow that properly. Here's my master.cf as modified:
    Looking at the how-to, it seems mine matches, no?

    Please put it in code tags instead of quote so we can see the indentation better :)

    Ahh, I see that I missed two uncomments. I fixed that and restarted postfix. I can now send mail successfully from local roundcube install to GMail but still receive no mail from GMail to the local email address. I'm running the test script again and posting the tail of mail.log:

    Did you create the user server for the domain adolf.schwimserver3.com?

    Yes, and I can send mail to GMail when logged into that account on the Roundcube install:

    Was I supposed to do something other than set up mail domain and mailbox in ISPC perhaps? Although I created the email address, I notice this in mail.log:
    Code:
    Jan  5 09:50:30 adolf postfix/smtpd[15037]: NOQUEUE: reject: RCPT from mail-ej1-f53.google.com[209.85.218.53]: 450 4.1.1 <[email protected]>: Recipient address rejected: unverified address: unknown user: "server"; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<mail-ej1-f53.google.com

    Can you try updating to 3.2.2 and reconfiguring services? If it doesn't work after, use a email test service like mxtoolbox.com

    Ran the update, choosing to reconfigure services and now at 3.2.2. Issue perisists. Mail from roundcube to gmail works, while mail from gmail to server never arrives. tail of mail.log shows the following:

    Toolbox shows everything as it should be.
    MX lookup: Network Tools: DNS,IP,Email (mxtoolbox.com)
    SMTP: Network Tools: DNS,IP,Email (mxtoolbox.com)

    All green checkmarks.

    One thing I've been wondering. When gmail mail fails because of status=undeliverable (unknown user: "server"), shouldn't that be user "[email protected]3.com"? since there could be a "[email protected]3.com", "[email protected]" and more, is that perhaps why this is failing? If so, what could be causing that issue?

    I just can't figure it out. I've tried making new email addresses and all behave the same. The address obviously exists because it let's me log into roundcube and I can send mail, but the error on incoming mail is always the same, unknown user. Why is my inbound server not seeing the accounts?

    If you want to manage email to addresses at adolf.schwinserver3.com, set the server's hostname to something different.

    That was it. It should have clicked with me when the user was missing the domain that it was equating the FQDN to be the same as localhost. Using an email address @schwimserver3.com results in mail moving back and forth without issue.

    Thank you all so much for your help, I can't tell you how much I appreciate it!
