server/email: use go-message for address parsing
No need to additionally depend on net/mail
server/email: don't panic in EmailRecover
A panic in here is not great, because this function is supposed to
be the panic handler. Let's just log the error instead.
server/email: log missing mail::error-to, treat empty string as unset
Log a message when mail::error-to is unset, just in case the admin
forgot to set it. Don't try to parse an email address if error-to
is set to the empty string (the default value in the default config
file).
server/email: simplify and cleanup
- Only print the error once
- Remove unnecessary var
- Use debug.Stack instead of hand-rolled logic
- Ignore json.Marshal errors in a simpler way
server/email: handle errors out of GQL context
server/email: include variables
Remove %e formatting verbs
%e is not valid for formatting error values:
> %e scientific notation, e.g. -1.234456e+78
Instead, use %w when using fmt.Errorf (for error wrapping) and
%v when using log.Printf (%w is not valid in that context).
Configure server to manage mail queue
This also sets up the recovery function for webhooks, so we get emailed
when we panic during a webhook query.
server: incorporate queue management
Import GQL server interfaces from gql.sr.ht
