Email Verification Fails and Exposes Sensitive Error Details

[Noryub]

Description:

• LinkStack Version: Unknown. Using an (official?) public instance: [linkstack.cc]
• Environment: Mozilla/5.0 (X11; Linux x86_64; rv:143.0) Gecko/20100101 Firefox/143.0

Steps to Reproduce:

1. Register a new user with an email like (anything)@pm.me.
   Note: @pm.me is an alias for protonmail.com.
2. Wait for the verification email (never arrives).
3. Click "Resend verification email".
4. An exception occurs, "getaddrinfo for mail.llc.ovh failed: Name or service not known", displaying full error details to the user (no obfuscation).

Expected Behavior:

• Verification email should be delivered successfully.
• Error messages should not expose sensitive information to end users.

Actual Behavior:

• Verification email is not received.
• Unhandled exception leaks internal error details.

Additional Notes:

• This issue may be specific to the linkstack.cc instance; behavior on other public instances is unknown.
