Original GitHub issue: https://github.com/dani-garcia/vaultwarden/issues/1862

When configuring the "From Name" with a ":" in SMTP Email Settings, f.e. "Example: Vaultwarden". Sender mail and name change to "nobody@invalid.invalid" on the receiving end.

I don't know if this is a specific problem with my mail hoster or if there is a quirk in retrieving the from_name from config or when setting up the e-mail.

I just tested a double colon : and that works fine for me.
It was sent using postfix and received by GMail.

You could btw, enable SMTP_DEBUG=true and see what is actually being sent out.

Then nevermind I guess and there is something wrong on my end. I will test with SMTP_DEBUG when I have time and reopen if it still persists.
