I'm using ActionMailer in Rails 3 to send periodic emails. I need to know whether an email was sent correctly (as far as it is possible to do so).
#lists.each do |list|
email = Reminder.deadline_reminder(list)
email.deliver
end
Is there a property of the email object (class Mail::message from the Mail library) that will tell me whether the send went correctly (no connection issues, authentication problems, etc)? I've looked through the classes on Github but haven't been able to figure anything out.
It all depends on what you consider successful.
You can test to see whether your code sent the message. You can often check the log to see if the mail-forwarding host received it and moved it on toward its destination.
But, only proprietary mail systems support delivery-receipts. SMTP doesn't and probably never will because of privacy issues and the inability of the mail-client vendors to agree on how to do it. So, even if it is delivered all the way to the intended destination there's no way to know if the person read it.
Your best bet is to put a link in the message that the user clicks which will tickle an app on the server with a token that was unique for that message. When the app sees the token it sets a flag letting you know they got the message AND at least read the part about clicking the link. Then, if there has to be a response within a given time you also track when the message was sent and escalate if the token wasn't received back within the time-limit.

I have created a app in Ruby on Rails in that I want to get the all updates of the gmail mailbox, I tried with push notification provided by gmail in this link https://developers.google.com/gmail/api/guides/push but in this we get only those message related to that topic, but if i want notification on my server for all the messages then what approach should i adopt,
Please let me know if any one have any idea about it.
The topic is a separate issue from what labelIds to get changes for. The reference for watch() says that if you don't specify any labelIds in the watch, then you will get all the changes to the mailbox.
I need a script that does the following: If any cell in a doc has been changed, then send email notification to custom address. I want the notifications sent every hour, not immediately (so if I'm editing the document- I don't want to get email every second...).
the current script I'm using is sending email notification for EVERY little change I'm doing...
Is that possible to send the notifications as a summary every hour or so?
I don't know if this is an acceptable solution for you. I did a work around for this. First I created a separate gmail account just to own docs. (This is because google does not notify when the owner makes changes.) I then forwarded the docs owner account to my outlook. In outlook I set up automatic forwarding rules to the address I wanted. I still have the problem of sending an email with every change but at least the people are informed.
I'm working on an iOS project. For this project I need an authentication system. However, if it's possible I don't want to use already built two-factor authentication systems such as Plivo or Sinch. I want to implement this feature of our application.
For this purpose, I need three things:
My application should get the phone number of the user and send it to server.
Server should send a sms to the number of user and my application should be able to read this message to get authentication code sent by server.
Application should be able to remove messages of this procedure from inbox and outbox of the iPhone used by user.
Now, i'm asking that can I implement this feature? I know this is a weird question but i've searched the Internet all day and could not get a certain answer. Thus I'll appreciate if someone informs me shortly.
Yes, you can that.
Your app can't read SMS messages received through the Messages app. The user would need read the message and note the code. Then switch back to your app where they could then type in the received code.
Your app can't access or modify any SMS messages received through the Messages app. The user would need to delete the message if they wanted to.
I have an app that sends email to registred users. This app sends an automatic email to the user while he is using some functions. Plus, on the admin screen, the admin can send emails to all persons that didn't get the email sent automatically for any reason. I store in database a value showing if the email was delivered or not, so the admin won't send emails to someone that already got one.
The problem is: how can I check if the email was delivered correctly in order to update this value? I am not talking about tests, I need to check right after the method deliver is called if the email was sent, or if any problem happened, like connection loss or email is invalid. Is there any method or way to do this?
Thanks.
When you send a message and no error is raised, you can assume that the mail was delivered (at least you can assume that some system accepted the responsibility to deliver your message).
Nevertheless, there are many reasons for delivery failure; sometimes you may get an error hours or even days later. You will need to have a bouncing mail address and inspect returned messages. If you want to process bouncing, inspect an open source software with bouncing treatment such as phplist. This is no so trivial as you might think.
Another alternative is send e-mails through a dedicated service such us SendGrid. This services provide APIs that will allow you to retrieve information about your messages.
You can also use the mailman gem to parse reply email messages for bad email.
I am using Active mailer to sending Emails,
I want to trace the mail ids which are bounced when i am sending the mails to the user.
Please give your valuable comments guys.
Thanks in Advance.

One solution is to use unique From-addresses when sending emails.
For example when sending email to user with ID 666, use the from address no-reply-666#example.com.
Then setup a script that receives the replies. If the reply is a bounce pull out the msg-id or whatever you need from the mail and store it.
Detecting whether the reply was a bounce or an actual reply from a real user can be tricky, because not all MTAs format the bounce messages properly.
An alternative to Postmark could be MadMimi.
I recently switch to using the email service Postmark, just so I could know about bounced emails better. They have a bounce api and support webhooks. I never could figure out a way to get that information back to my app from the MTA I had running. It is a pay service so it might not work for you, but it has been useful for my project.
There is a good explanation in Recepie #70 http://www.pragprog.com/titles/fr_rr/rails-recipes
