Basically, every single Gmail, Microsoft Outlook, and Zoho email IP is on sorbs. Each IP is shared by 1000s of users. So if you using these major email providers SORBS is nothing you should worry about.
If your domain is on SORBS or any other blacklist, that is worrisome. Just check your domain on mxtoolbox and you will know.
Never use your primary domain for outbound. Keep less than 50 emails a day. 40 outbound emails, and 10 warm-up emails. Have the necessary records, DMARC, DKIM, and SPF and you are all set. To conduct tests, better use GlockApps.
