I want to use SendGrid to receive emails. Here is my scenario.
User A will send an email from user-a#example.com to User B at user-b#example.org
I've setup a rule so that emails received by User B are forwarded to c#example.net.
example.net is my domain and I have configured example.net in SendGrid to point to an MVC controller which will process the JSON posted by SendGrid.
Is this possible? I was able to receive one email but after that it stopped working. What went wrong? Can any one help me out?
The problem was solved via a different channel. The resolution can be found here: https://community.sendgrid.com/sendgrid/topics/receiving_forwarded_mails_send_grid
Through using a number of debug tools, including RequestBin and Runscope, the user found there was an error in their controller, rather than an error in forwarding or message parsing.
We were able to debug and find the problem which as you predicted was with our controller.
We are still testing by sending mails from various domains but have not come across any mail that is getting lost.

Is there any way to find whether the email is legitimate or not. I am using mandrill and some emails were hard bounced so, is there a way where mandrill can send a response to my rails application that email was hard bounced. Or is there any other way to find that email actually exists or not through other medium. I saw a gem https://github.com/kamilc/email_verifier but there were some issues so I am not sure to use it or not.
Thanks in advance for help
I think you are looking for Mandrill's webhooks
The idea is that you set up an endpoint to receive event notifications (including bounces) from Mandrill.
One best solution is to implement webhooks which returns all status of emails sent. The webhook can be customised to recieve what response you can recieve including sent and delivery also. It also helps in tracking open and click rates which could be later used for filtering privileged users.

I am using free mandrill account and sending email via using template and API
When i send message it returns okay it is sent as status
However even after several days there is still no smtp events at mandrill interface and the email is not arrived
So i am 100% suree mandrill is ghosting accounts
Or there is something else that i do not know?
Thank you for answers
PS: At the beginning emails were arriving but after some point no smtp events and no emails ever arrived even though no error message parsed. Also when i send to non existing email no bounce message returned.
Also account reputation is 61 : excellent
Yes i believe mandrill certainly ghosting accounts
After trying with several accounts i am now sure of it
Even if you send to non existing gmail email, it says delivered in its interface
However it should have displayed hard bounced
So beware of their free service. I believe this is not an ethical way of working. People would think that their emails are arriving however they are ghosted and mandrill did not even try to send them and yet displays delivered
Have you check it on Mandrill account? It shows all the report at outbound tag. The reason is, a queued response in the Mandrill API is not the same as a queued response from a recipient server.
When you send a message through Mandrill, you first relay it to Mandrill, Mandrill processes it, and then Mandrill relays it to the recipient server. This all happens quite quickly, but the two relaying steps are separate and distinct. The KB article you've linked to is providing additional details on that last step, relaying to recipient servers, not a queued status for the Mandrill API.
There are a number of reasons the Mandrill API may respond with queued including if you've added attachments or if you're sending to a bunch of recipients in a single API call.
Without seeing the actual API call that's being made, it's hard to say why you're getting a queued response. But if you're using the sample messages/send API call, you'll want to remove all of the optional parameters that you're not actually setting. For example, the sample has fake attachments, and a subaccount specified. The attachment will cause the call to be processed async. The subaccount probably doesn't exist, and would then cause the call to fail. So if that's the case, try removing all of those optional params. If not, please provide the API call you're making with sensitive data redacted (API key, actual email addresses).
I'm trying to send email from my app, emails seem to be going to mandrill correctly and there getting delivered, but I see nothing in my inbox.
I've even tried sending them through my domain and I'm still not getting them. I get them from my live website its using gmail but I want to switch
Using mxtoolbox.com I found
SMTP Reverse DNS Mismatch and
454 4.7.1 Relay access denied which could mean its been marked for spam?
It's sent through emails twice so I'm wondering if theres a time between emails sent or something.
When I was testing this I thought my emails where being dropped by gmail. I found that for some reason there was a very long lag going from Mandril to Gmail. I received all my tests about an hour after Mandril sent them. Hope this helps someone stuck like I was.
Found this question trying to diagnose my issue.
I am using Mandrill and found that sending emails from Mandrill to Gmail will take anywhere from 10 seconds to 15 minutes. Can't establish a reason why sometimes it takes longer.
Mandrill blocks certain domains from being the send address to prevent fraud, but as long as you're sending from an address you know exists to an address you know exists, you should be fine. Also, if that were the problem, the email would bounce rather than send. Also, some email services have policies that prevent you from doing things like sending an email to your address from your address from an external service. Based on that error message you provided, it could be something like that; I would check your provider's policies (and your spam folder).
Not an answer but if you look on your mandrill Outbound activity page and click on the green icon that says Delivered you should see that it says No smtp events.
I don't know why it doesn't send but this show that it hasn't sent.
Or should I say hasn't arrived where it was supposed to.
Update:
On further investigation I found out that the emails weren't sending because I was using my personal email address as the sender from_email: When I changed this to a more business sounding email address it worked. So make something up if you have to, like no-reply#nonsense.com
When using 'mail' command to send email to a gmail user, the email goes through fine. When sending an email using a Rails app, the email is sent to the spam folder for the gmail user. Can someone help me think through this?
Emails landing in SPAM can happen due to many reasons:
Wrong Mail Server setup: Checkout here on how to setup
Email content: Content of the email can also invite SPAM. Sites like SpamCheck helps to check whether the content of the email is ok.
As mentioned by #Noli above, using services like Sendgrid, Critsend etc for sending out emails, chances of landing them in Inbox will be more. You can use them as relay servers from Postfix. But the first two steps are anyway necessary.
Use Mailchimp if you want to sent emails to many people, for eg: for sending out newsletters, marketing emails etc.
Mail deliverabillty is extraordinarily hard to get right. You should consider leaving this to the specialists like Sendgrid or Mailchimp, and not spend tooooo much development time thinking about it
Another thing to check is that if this is a new server, you may need to set up Domain Keys to authenticate to Gmail. This happend to me and I was able to get my mail removed from the spam folder by following these:

I have application that needs to send emails and sms text messages. It sends emails just fine, but when I try to send text messages using email gateways (for verizon, xxxyyyzzzz#vtext.com) I get nothing. I have texted the phone using though the email gateway using my gmail account, so I know it works. I would just think that from my app's point of view I am just sending out another email. Any idea why this doesn't work? Or what I can do to troubleshoot it?
I should also note that I am doing this from a Rails app on my local computer...not that it should matter.
Maybe Verizon has software that can identify emails sent from software rather than humans, and rejects yours?
Try making your software add all the same headers (eg. X-Mailer) that a normal email client would add.
Verizon could be doing a reverse DNS query as a simple spam check. Your ISP's info could show up during this look up instead of the return address info that your email message contains, and thus could be getting blocked.
To troubleshot this make sure that the return e-mail address that you are using is coming from an ISP e-mail account.
Here is how to debug it on Linux. Run your Rails application server with strace:
strace -s99999 -e connect,read,write,close -o strace.log script/server
Then examine strace.log and see exactly which SMTP server the Rails application connects to, and what it reads and writes.
Then do the same with your favorite mail client (recommended: mutt, because Thunderbird is slow in strace).
Try to send exactly the same bytes from Rails what your mail client sends.
I have used SMS_Fu in the past to send out text messages. It has worked wonderfully.
I have written a client app for Ruby for sending SMS, please see http://freebiesms.blogspot.com/2009/07/send-free-sms-from-ruby.html to download
