86. How do I set up an MX record for Hostilla mail?
The MX record points to the server that receives mail for the domain. To use Hostilla email, set your MX according to your hosting service's configuration and make sure your domain is using the correct DNS zone.
After changing the MX, wait TTL and perform a reception test from the external box. If your email has been migrated, check the old service for some time as well.
87. How to set SPF in cPanel?
You set SPF as a TXT record in the domain's DNS. The record should indicate servers authorized to send mail on behalf of the domain, including Hostilla servers and any external newsletter or invoicing systems.
Don't add multiple separate SPF records for a single domain. Typically, there should be one SPF record connecting all eligible sources.
88. How to generate DKIM in cPanel?
DKIM is usually generated in cPanel in the email authentication or Email Deliverability section. After enabling DKIM, the system will show a TXT record that must be included in the domain's DNS if DNS is not automatically handled on the same server.
After the change, check with a test whether outgoing messages are signed. DKIM is important for deliverability and protection against domain spoofing.
89. How to set up DMARC?
You set DMARC as the TXT record for_dmarc.twojadomena.pl. You can start with an observation policy and gradually tighten the policy after analyzing the reports.
DMARC works best when SPF and DKIM are correct. Too restrictive a policy set without testing may result in rejection of legitimate messages from the CRM, store or newsletter system.
90. How to check if SPF, DKIM and DMARC are working?
You can check SPF, DKIM and DMARC using DNS tools and a sending test to an external mailbox. The results should appear in the news headlinesspf=passdkim=passand appropriate DMARC assessment.
If the result is negative, check the DNS zone, TXT records, the SMTP server used, and external systems sending on behalf of the domain.
91. How to connect an external newsletter system?
The external newsletter system must be authenticated in the domain's DNS. Most often, this requires adding SPF, DKIM, CNAME or TXT records provided by the mailing system.
Do not send newsletters without domain authorization, because it reduces deliverability and may look like spoofing. After adding the records, perform a deliverability test and check the message headers.
92. How to authenticate a domain for shipping in MailerLite or similar system?
The external newsletter system must be authenticated in the domain's DNS. Most often, this requires adding SPF, DKIM, CNAME or TXT records provided by the mailing system.
Do not send newsletters without domain authorization, because it reduces deliverability and may look like spoofing. After adding the records, perform a deliverability test and check the message headers.
93. How to configure shipping from the invoice/CRM store via SMTP?
The invoicing system, store or CRM should send messages via authenticated SMTP or via a properly authorized external shipping system. In the configuration, enter the full e-mail address, mailbox password, SMTP server, port and encryption.
After setup, send an invoice or test message and verify that the domain has the correct SPF, DKIM and DMARC.
94. What to do when messages end up in spam?
If messages go to spam, check SPF, DKIM, DMARC, message content, domain reputation and IP reputation. Links in the message, attachments, signature and compliance of the sender's address with the domain are also important.
In Hostilla you can analyze headers, stanzas, shipping logs and anti-spam reports. Please include full sample message headers with your report.
95. What to do when messages come back with errors?
If messages return with an error, the full SMTP verse is most important. It contains the error code and whether the problem is with the recipient address, reputation, DNS, SPF/DKIM/DMARC, limits or message content.
Send the entire verse to support, not just the first sentence. Also provide the sender, recipient, date and time of shipment.
96. What to do if the message has not arrived and the recipient says there is nothing?
Hostilla can check whether the message has been forwarded and received by the recipient's server. If the recipient's server has accepted the message, further filtering, spam folder or user rules are done by the recipient.
To check, we need the sender, recipient, date, time and subject. This helps you find the entry in the logs and confirm the delivery status to the recipient's server.
97. How to check delivery confirmation to the recipient's server?
Hostilla can check whether the message has been forwarded and received by the recipient's server. If the recipient's server has accepted the message, further filtering, spam folder or user rules are done by the recipient.
To check, we need the sender, recipient, date, time and subject. This helps you find the entry in the logs and confirm the delivery status to the recipient's server.
98. How to parse a full SMTP verse?
The full SMTP verse shows the path and reason for the message failure. Look for an error code, server name, SPF/DKIM/DMARC information, IP reputation, non-existent address or disapproved content.
Do not shorten the stanza in your application. One line is often not enough because the details are located lower in the report.
99. How to analyze news headlines?
Message headers show message route, SPF/DKIM/DMARC scores, intermediate servers, and anti-spam rating. In your webmail or email program, select the option to show the message source or original.
Full headers are needed when analyzing spam, spoofing, latency, and deliverability issues.
100. What does IP listing on RBL mean?
IP listing on RBL means that the IP address has been included in the reputation list used to combat spam. This may affect mail delivery to some recipients.
The cause may be spam mail sent to the mailbox, an infected form, poor reputation of the sender or incorrect configuration. You need to remove the cause and only then report the delisting.
101. What anti-spam lists do we use?
Hostilla uses a number of reputation lists and sources, including commercial lists such as Invaluement when used for a given protection layer. Reputation lists help you reject spam, phishing and known sources of abuse.
