I'm using GMail's API: Users.messages: insert, in order to insert EMails into my GMail mailbox.
Additionally I've configured mail forwarding from my mailbox to another GMail account.
Unfortunately the mail inserted with GMail insert API are not forwarded.
Will be glad for any help on that subject :)
Use users.messages.import() to upload messages and have forwarding rules executed on them. insert() bypasses most of the automatic mail processing, including forwarding and filters.

All I have is an email client (emClient) and a working sendgrid account. When prompted to enter an email address, I can happily put anything#mydomain.com and it will confirm that it works with SMTP. I can also send emails using this client. I authenticate with the username apikey and my api key.
However, these emails are permanently stuck in the "outbox" and are constantly sent over and over again, presumably because the client has no confirmation that they were sent. When trying to set up a new account under this domain, I setup my "incoming server" as smtp.sendgrid.net and provide my credentials and it sort-of works (after prompting me for my authentication?).
As you can see, SMTP authenticates just fine and this makes sense as I am seemingly able to send email. However, both IMAP and POP3 when I select them in the "incoming server" are stuck on this "testing" stage until they fail.
Now, if we skip ahead to me sending something out - basically, it works. I receive the email on the destination, it does not get marked as spam and it comes from my domain and my name.
However, when I attempt to receive an email on the anything#mydomain.com one, it just doesn't do anything. I don't get an error from gmail that it wasn't delivered, it simply just doesn't get delivered.
For my domain settings, I have the following configured:
Twilio SendGrid developer evangelist here.
While SendGrid allows you to send emails over SMTP or via the API, SendGrid is not a full mailbox that you can connect to over POP3 or IMAP. You cannot connect to SendGrid using an email client, that is not what it is intended for. SendGrid is not a mailbox, but a way to programmatically send and receive emails and other email based events.
The way to receive incoming emails is via the inbound parse webhook. When you have set that up, incoming emails to your configured domain will cause a webhook, an HTTP request, to be sent to a URL you configured, with all the information about the email.
I want to send mass email with GMail API.
Currently I add all the addresses at the To section.
But every recipient should receive the mail and see only his address and not the other ones. Is there a method/API that I can use for this?
As far as I know, Gmail was not created for sending bulk emails as it restricts the number of recipients and has tons of other limitations. You should try to use third-party service for this.
Here you can find Gmail API limitation. It says
100 Recipients per message sent via SMTP (by POP or IMAP users) or the Gmail API
I tried to send an email through sendgrid. I have a custom domain myself#contoso.com. If i try to send an email to user1#gmail.com with the from address as myself#contoso.com,then,the email is delivered to gmail with "via". When i try sending email to myself#contoso.com with the from address being myself#contoso.com the activity says the email is delivered however, in outlook client i have not received the email. What is it that I can try or do?
I have tried whitelisting contoso.com but it did not work
This is not an answer, as it doesn't help work out why the emails that are "Delivered" have not been received, but this is SendGrid's note on why Email messages with the “Delivered” status are not received:
Twilio SendGrid posts the Delivered event after the destination server accepts the message with a 250 OK response. Once an email is accepted by the destination server, we are unable to see what happens to the message. The receiving server could send it to the inbox, queue it for later delivery, put it into the spam folder, etc.
Often times, a recipient domain will initially accept a message for delivery, and then apply additional filtering afterwards. In this situation, we would have posted the Delivered event, but not have any insight into the additional filtering. Any additional Twilio SendGrid events for your email message would be triggered by recipient engagement (i.e. open/click events, unsubscribes, etc.).
Also note that at the time of writing, that answer had 26 downvotes (and zero upvotes) on the SendGrid website, probably indicating that many other users have experienced this problem.
I had several issue solving this problem. The most important part is to set "Sender Authentication" from sendgrid to your domain dns. There is a instruction here. I'm using godaddy, so the link to set dns is https://dcc.godaddy.com/manage//dns .
A bot has found a way to send bulk spam through my server. My server is not an open relay. All mails are coming from localhost. The emails are being sent from a series of FIRSTNAME_LASTNAME#mydomain.com. At mydomain, there is only 1 email account that was created that we send from.
Is there a way to restrict outgoing email that are being sent through exim to only allow emails to be sent from the 1 email account we created and block all other Sent From addressed that are being created?
You have to add the next condition to your SMTP router(s):
condition = ${if match{$sender_address}{legal#mydomain.com}{yes}{no}}
I was able to resolve this by turning on X-Headers which allowed me to locate where the emails were being executed from which in turn allowed me to eliminate an exploit from an old script.
I want to use Mailgun to send/receive messages programatically via API.
BUT I need to have also some mailboxes available using Thunderbird or other mail client.
For example I want to have user mailboxes at:
support#
sales#
admin#
And all other e-mails will be for API send/receive.
I can not forward my mail to GMail because I need to reply from the same address (sales#mydomain.com).
Please help.
There is a limitation to using the routing feature and that is that if you delegate a domain to be used by Mailgun you cannot use it with an email client.
That means that, for example, if you want to route emails to user#domain.com and then still use that email address with your favourite email client (be it Thunderbird, Outlook or Gmail) you can't do it. That is because of the way you've configured your MX records (email records in your DNS).
When you use Mailgun's routing functionality you delegate MX records to mailgun, which receives your emails, parses them and routes them according to your preferences.
So how do we solve your problem?
What you can do instead is set up your MX record on a subdomain.
Using subdomain.mydomain.com and pointing its MX records to mailgun will allow you to receive and parse emails through Mailgun.
This way you can have:
admin#subdomain.mydomain.com
sales#subdomain.mydomain.com
etc
will be handled by mailgun
while
admin#mydomain.com
sales#mydomain.com
will be handled normally with your email client.
Please do not hesitate in asking more details!
You need to configure your MX record settings for your subdomains in your DNS control panel.
