You should not send professional emails using your personal Yahoo, Gmail, Outlook, AOL, etc. in the FROM address. The emails might:

  • not be delivered at all, like on Yahoo,
  • or display a warning, like “Be careful with this message” on Gmail which warns about the recipient that he might be spoofed.

It's still possible to use the SMTP with a MTA configuration. See for instance postfix SASL solution but I don't known the repercussion. You should test it.

Dedicated Server

On a dedicated server, you may send:

  • via the installation of a MTA
