Can receive but not send emails out

Your rDNS for 194.163.155.218 looks good, as it is pointing to the hostname vps.klarys.net as it should.

You have an MX entry for klarys.com

The SPF record is there, and looks good.

DKIM look good:
default._domainkey.klarys.com

DMARC is set to Reject & Strict, which is fine, but you don't have an email address entered to receive reject reports.

What where the errors mail-tester were giving to you?

Seriously, I am a novice in this (with my head filled with programming languages and none of networking) so I deperately need help in this as it has become critical to my work.

Now, should i replace/add the mail.klarys.com with the vps.klarys.com (ie mail.domain.com with vps.klarys.com)??

The mail tester was giving me the following errors:

Your email client, plugin or extension said "sent", and it sure did. But your email got stopped just after, and never got sent.
Why? Your SMTP or web host is probably blocking your emails. Quite common. Get in touch with them now to find out.

Contact your upstream & double check your TCP_IN & TCP_OUT in the firewall.

As it mentioned, it's being blocked somewhere.

 I find the following there:

Code: [Select]

# Allow incoming TCP ports
TCP_IN = "20,21,22,25,53,80,110,143,443,465,853,587,993,995,2030,2031,2082,2083,2086,2087,2095,2096"

# Allow outgoing TCP ports
TCP_OUT = "2703,20,21,22,25,53,80,110,113,443,2030,2031,2082,2083,2086,2087,2095,2096,853,587,993,995,2080,2443"
 

Try adding port 465 for SMTP.

Also try disabling csf/lfd, and if outgoing email doesn't work, then that would point to the upstream blocking ports somewhere.

Can you resolve this for me for a little fee?

Try to rebuild your mail server, if that fails let me know.

If you want I can login and took a look, but won't charge you.

Thanks so much, I rebuilt it and still same. Also, I don't mind if you help me out with this, i desperately have to solve this issue.

Just fought with another server tonight, nothing was wrong.

Turned out the provider was at fault...
Even though they said they had opened port 25...

CLI test wouldn't even go out.

Spoke to a 3rd support person, and don't know what they did, but the tests started flooding in after 4.5 hours...

But I can look at it.
Do you have an encrypted email account using OpenPGP?

No. Honestly I don't know if I have it or not because this is the first time hearing it.

I just did a small research on the openPGP and I can say I have a gmal account and I run that and all other on thunderbird which apparantly is based on the openPGP.

Is that enough?

If you have OpenPGP installed in Thunderbird, it should give you an option at the top to 'Encrypt' the email.

I never recommend sending password over PM or UnEncrypted methods.
But sometime it has to be done.

Set a temp password, and send me a PM.

Then afterwards you can reset the password.
