Describe the Bug

Testing out a new instance of BookStack, I setup the mail configuration as such:

MAIL_DRIVER=sendmail
MAIL_FROM_NAME="No Reply @ My BookStack"
MAIL_FROM=noreply@.

I tried the configuration using the Send Test Mail feature from the Maintenance settings.
I properly received the test mail on the gmail account of the user.
After enabling registration (and using Domain Restriction as well), I tried to setup a new user account. It did not return any error but I never received the confirmation mail that I required to activate the account.
Upon trying to login with that new account, the account is still not activated (which is expected), and I'm offered to send the mail again. Doing so does not solve the issue either.
I have checked my spam folder and other email addresses to no avail, though it should've worked regardless since the test email is successful (and does not go to the spam folder either).

Steps to Reproduce

Install BookStack
Configure the Mail System using the sendmail driver in the .env file
Create a user account from the UI Settings using a working email
Log in to that user account
Use the Send a test mail from the Maintenance settings
Enable registration
Log out and create a new account using the registration interface
Check your emails for the expected activation email

Expected Behaviour

The user created through the registration interface should receive the activation email in their mailbox.
