[Solved] Cannot receive e-mail

[jchang]

I'm using thunderbird with the following settings:

SMTP Server

Server Name: jchang.heliohost.org
Port 465
SSL/TLS
Normal Password

User Name: bsf@jchang.heliohost.org

Identity:
email address: bsf@jchang.heliohost.org

Reply-to address: bsf@jchang.heliohost.org

The daily limit of 250 was not reached, but the default 10 emails per hour limit was exceeded. I have changed the limit for bsf@jchang.heliohost.org to 250 per hour, but keep in mind if you create any new email addresses they will have the default 10 per hour limit unless you request us to change them as well.

Thank you!

Sorry to bother you again.  Thanks for getting the e-mail setup.  I'm having problem with some people finding my e-mail going to their spam folder.  I'm trying out a service https://resend.com  and it's trying to authenticate the DKIM and SPF.

I saw another request in this forum that is asking for those services to be activated:

I'm not using a special domain, just the default bsf@jchang.heliohost.org  Do I need SPF/DKIM to be setup?

Please excuse my ignorance, I'm trying to learn this as I go

The mailtester website flagged the following items:

-0.1	DKIM_INVALID	DKIM or DK signature exists, but is not valid
-0.1	DKIM_SIGNED	Message has a DKIM or DK signature, not necessarily valid This rule is automatically applied if your email contains a DKIM signature but other positive rules will also be added if your DKIM signature is valid. See immediately below.

-1.284

RCVD_IN_RP_RNBL

Relay in RNBL, https://senderscore.org/blocklistlookup/

-1.274

RDNS_NONE

Delivered to internal network by a host with no rDNS This may indicate you do not have a rDNS configured for your hostname or the rDNS does not match your sending IP

-0.896

SPF_HELO_SOFTFAIL

SPF: HELO does not match SPF record (softfail) softfail

We were not able to retrieve your public key.
Please ensure that you inserted your DKIM TXT DNS record on your domain jchang.heliohost.org using the selector default.
If you recently modified your DNS, please be patient and test again your Newsletter in 12 hours, it may take some time for the DNS to be propagated

-------------------------------

You do not have a DMARC record, please add a TXT record to your domain _dmarc.jchang.heliohost.org with the following value:

v=DMARC1; p=none

Verification details:

• mail-tester.com; dmarc=none header.from=jchang.heliohost.org
• mail-tester.com; dkim=fail reason="key not found in DNS" (0-bit key; unprotected) header.d=jchang.heliohost.org header.i=@jchang.heliohost.org header.b=GGPGUB8J; dkim-atps=neutral
• tommy2.heliohost.org; spf=pass (sender IP is 67.180.36.93) smtp.mailfrom=bsf@jchang.heliohost.org smtp.helo=[192.168.1.17]
• From Domain: jchang.heliohost.org
• DKIM Domain: jchang.heliohost.org

Your IP address 65.19.154.92 is associated with the domain 3(NXDOMAIN).
Nevertheless your message appears to be sent from tommy2.heliohost.org.

You may want to change your pointer (PTR type) DNS record and the host name of your server to the same value.

 

Here are the tested values for this check:

• IP: 65.19.154.92
• HELO: tommy2.heliohost.org
• rDNS: 3(NXDOMAIN)
