Hi. I'm just wondering if WHMCS has any issues sending out emails to addresses with apostrophes? A support contact is not receiving any WHMCS ticket responses and the system logs confirm that WHMCS isn't even attempting to send them out:
Email Sending Failed - Invalid address: (to): example'name@example.com (Subject: [Ticket ID:...])
While not too common, and not advisable, an apostrophe is a valid character in the username section of the address.
Any insight would be appreciated. Thank you!
