Model Indicators for Message Identification (BIMI) is among the newest options proposed to assist mitigate enterprise e-mail compromise (BEC) assaults. Under we’ll cowl the whole lot it's good to learn about learn how to create a BIMI file in Management Net Panel (CWP), previously CentOS Net Panel.

Right here’s a BIMI DNS file instance:
default._bimi.instance.com 3600 IN TXT “v=BIMI1; l=https://instance.com/brand-name-logo.svg; a=;”
Create a BIMI Brand File
Step one to creating a picture that meets the BIMI commonplace is to search out an software that may export to SVG Tiny 1.2 specification. The preferred ones at the moment are Adobe Illustrator and Inkscape. There are some free conversion instruments accessible as properly. The BIMI Group, which develops the usual, launched conversion instruments for Home windows and macOS named SVG P/S Converter on GitHub in 2020. Listed below are some fundamental tips:
- No embedded pictures (png, jpeg, and so on.)
- Have a background coloration (no transparency)
- Sq. dimensions (e.g. 15x15px or 200x200px)
- No rasterized knowledge

Add the File to CWP
After changing your emblem to a tiny SVG file, add it to your CWP server.
- Log into CWP.
- Choose FileManager on the high of the display screen.
- Use the left-hand sidebar and navigate to the basis listing to your web site. Use the Checklist Domains part to evaluation the web site root listing if crucial.

- Open the URL in your browser to make sure the picture is publicly accessible. In the event you uploaded the picture to your web site root listing, the URL ought to resemble “yourdomain.com/brand-name-logo.svg.”
- Shut the CWP file supervisor.
The way to Create a BIMI Document
After confirming the BIMI picture URL works, it’s time to create the BIMI DNS file.
- Again in CWP, choose Checklist DNS Zones from the sidebar.
- Choose Edit Information for the e-mail area receiving the BIMI DNS file.
- Scroll to the underside of the web page. Guarantee there are DNS data for SPF and Area Key Recognized Mail (DKIM). DKIM is optionally available however works with SPF to inform different e-mail servers when mail marked as out of your area is legit or a spoofing try. The SPF file worth will begin with “v=spf1” whereas the DKIM begins with “v=DKIM1.”
- If the SPF or DKIM data are lacking, open the MailServer Supervisor from the sidebar in a brand new browser tab.
- Examine the field for Set up DKIM & SPF (beneficial) and choose Rebuild Mail Server. Reload the DNS zone editor web page. If a DKIM file nonetheless doesn't exist, it's possible you'll have to troubleshoot the OpenDKIM bundle. Or you may proceed with out it for now.
- Guarantee a DMARC file is current. It's going to embrace “v=DMARC1” within the worth.
- Scroll as much as the “Add New Information” part and choose “TXT” from the “Document Sort” drop-down menu.
- Sort “default._bimi” for the file title. We advocate utilizing “3600” for the TTL. Then add the BIMI file worth, changing the picture URL as crucial:
"v=BIMI1; l=https://instance.com/brand-name-logo.svg; a=;"
- Choose Add Document TXT.
When the checklist refreshed throughout our testing, solely “v=BIMI1;” confirmed within the worth column. To verify the BIMI file was current, test Checklist DNS Zones > Edit File. This opens the uncooked DNS zone file for the area. The underside line ought to resemble the next:
default._bimi 3600 IN TXT “v=BIMI1; l=https://instance.com/brand-name-logo.svg; a=;”
