Ability to "send mail as" from Gmail

[niftylettuce]

We'd need to enable AUTH command and add onAuth option via https://nodemailer.com/extras/smtp-server/#handling-authentication. Perhaps we only allow sending mail as from Gmail for now?

[kitlith]

for password based auth, one way would be to store the hash of the password as a TXT field on DNS. however, I don't think this is a very good idea as it could lead to offline hash attacks.

therefore, I suggest some PKI scheme (PGP?), encrypting the hash before sending it to putting it on DNS. That way, the only one that can decrypt the hash is the one running the server, and then a normal password hashing scheme can be used on top of that.

Curious what the status on this is? This is the only thing blocking me from using this because I'd also need to send email under the address!

Thanks for the awesome work!

Hi! Can you give some help about just that that @mendelk had said? After correctly forwarding emails for my gmail account, when trying to send emails setting smtp configs, I am getting "550 Message failed: 550-5.7.1 Unauthenticated email from google.com is not accepted due to domain's". And I don't know how to proceed hahah
Thanks in advance!

@niftylettuce discovered your service today, moved 3 SaaS over it, awesome piece of work! Really.
Highly interested by this, how much would it costs for you to implement it?

[niftylettuce]

@FGRibreau I've already begun this feature along with #3 😄

@niftylettuce, thanks, can't wait. This will be really useful for my business as I'm not really ready to get GSuite.

[FGRibreau]

@niftylettuce any way we can help? Could you share the branch with us?

I plan to dedicate time this weekend, wrapping up work for my company right now 👏

@niftylettuce using 'send mail as' from Gmail should already be possible using Gmail's own SMTP without any modifications on forwardemail's end (for example see this guide). However, this currently fails at the verification stage, as forwardemail rejects the verification email from being forwarded due to DMARC authentication. Is there no way to work around this? If it was just possible to get the verification code which currently gets blocked, this should be working fine.

✅ support has been added and deployed, please try it out

documentation is available at https://github.com/niftylettuce/forward-email#send-mail-as-using-gmail

Successfully went through all the steps including the verification step, while using and IDN domain. However, when sending email using this domain get the following error from Google.

Final-Recipient: rfc822; destination_address@gmail.com

Diagnostic-Code: smtp; [209.85.220.41 11] Our system has detected that this message is not RFC 5322 compliant: 'From' header has non compliant domain name.

So it looks like Google's SMTP server does not support IDN domain names and there is nothing forward-email can do about it. Maybe add a sentence to the documentation mentioning that?

[niftylettuce]

This issue and all related ones should be fixed now as of today by the way everyone!
