My custom name instead of the topic name

[Yaro7619]

Hi.
💡 Idea
It would be nice to have the option to provide a custom name instead of a topic name, like in most e-mail clients.

Now, recipients receive an e-mail from a sender named:
domain.tld/topic [email protected]
It would be nice to have format like this:
Custom Name [email protected]

ntfy/server/smtp_sender.go

Line 115 in 630f295

body := `From: "{shortTopicURL}" <{from}>

💻 Target components
ntfy server
