Custom Email “From” Configuration

I use the standard webmail interface that came with my hosting plan and I want every message I send to show a custom “From” address tied to my own domain. This is for personal correspondence, so it doesn’t need complex marketing features, but it must look polished and work reliably.

What I need you to do
• Configure the account so the custom address appears correctly in all outgoing mail and passes basic deliverability checks (SPF, DKIM, etc., if required by my host).
• Create and install a clean-looking custom email signature that automatically appends to new messages and replies inside webmail.
• Supply concise, step-by-step notes so I can edit the signature or reapply the settings later if I change devices or providers.

I’ll provide hosting panel access, domain details, and any DNS control you require as soon as we start.
