Fix contact form

[danielstreif]

The contact form has not been working since we moved to DigitalOcean because by default SMTP port 25 is blocked. This should prevent the use of DigitalOcean domains to send out spam emails (see https://docs.digitalocean.com/support/why-is-smtp-blocked/).

The suggested workaround is to use SendGrid. I've created an account with our dev address there and followed these docs to set everything up.

I've already changed the env vars so this should work once the PR is merged. Let me know if there are any questions.

SendGrid requires fromto be identical with the verified email address, so an additional replyTo field is necessary to actually reply to the person who sent the contact request via the form on the website.

Hi 🖖

Great to see you found an answer 🚀

A couple of remarks:

• Does it mean that Digital Ocean was blocking port 25 outgoing traffic? We didn't host a mail server 😅
• I assume that some of your code wasn't yet pushed, since sendgrid requires a new library instead of nodemailer, according to the docs you mentioned.

Hi Olzhas, thanks for the quick response! I guess I didn't draw the right conclusion then with the port 25 issue. I thought we are using the DigitalOcean domain as a mail server since we have the MX values set there. Not on my machine at the moment but I can look into it later on.

That aside, using SendGrid did fix our issue. I posted the wrong docs link though (multiple tabs open), sorry for that. I actually followed these instructions, no additional library required.

Locally everything works fine and I can use the contact form.

Edit: I am aware we aren't using DigitalOcean as a mail server but we are routing through it, right?

@pheeria a bit more information how I got to the current state of this PR:

The error we get when trying to send an email is 535, so an authentication issue. The credentials are definitely correct, so it might be a configuration/security settings related problem. I first checked our email provider but couldn't find anything there. Port etc. were set correctly.

As we are routing the emails through DigitalOcean I followed their suggestion to use SendGrid and it worked. Do we want to go with this solution or find another way?

If this works, then let's go with it!
We don't run our own mail server, it's still on United Domains, however the domain is managed by Digital Ocean, hence you see port numbers in domain configs.
