I faced a problem with 'Email to Salesforce' functionality - emails sent from email addresses with subdomain don't become associated with records.
I added several emails into "My Acceptable Email Addresses", for all the emails everything works well and Salesforce receives them well except email with subdomain (format [email protected]). For those with the format [email protected] everything works as expected.
No domains were added to "Excluded Domains". I also checked the "Unresolved Items" configs - nothing there. Email messages that should be added to Salesforce are identical as for subdomain email and non-subdomain email And, just in case, it's under the System Administrator user, all permissions are granted.
I didn't find any topics related to issues with subdomains, would be very grateful for any recommendations!
