As the title says, I would like to know if there is any way to send emails without having to use an external service, that charges me for sending the messages, or having to use an SMTP server in which each user has to be registered.
I have also seen pages like email.js but I don't want to have to pay for that if there is a possibility to do it on my own. It is also not useful for me to open the Gmail or messaging application of the device itself since I already know how to do that and it is not what I want.
For better understanding, I will give an example of what I want to do.
What I want is that from my application the user writes a message and from there that email message is sent to several different users from a list, without having to log in or anything, since the emails will be sent from my own email account. gmail that I have specifically created for the application.
I have seen the smtp server but from the information that I have seen that server implies that I have to log in to be able to have the token and that is not what I want because I want that once I configure everything there is no need to do anything else that people receive your messages and that's it.
I don't know if this is possible but I hope someone can help me.
Sending emails without your user logging in would require you to have either the credentials stored in the app (which is unsafe) or use a custom backend server that will host all the credentials that cannot be extracted. I would advise going with the backend route because it is easier to setup and your application will simply perform a HTTP request to get it done.
From the documentation of the mailer package, you can implement the server method pretty easily and get it moving. You will have to find a free web hosting service to deploy to.
There would really be otherwise no other way to get what you desire for virtually free.

Was hoping for some ideas as to a service to which I can set up an inbound-only email system. In other words, I will have multiple users on the system, each can receive their own email... but at the moment... at this time, I am not focused on the ability to send or reply to messages, only receive them and send to the appropriate user. I looked into Postmark... They seem to have some great functionality.
CloudMailin Is another alternative. However there are effectively three options for setting up something like this.
Use an existing, traditional, email server and poll for the emails
Setup your own email server and create a script to run when you receive an email
Use a third party solution, as you've already mentioned.
I went through for of these for Rails a little while back here, but all the information is still relevant.
Although Apple doesn't allow apps to send text messages without explicit user permission (unlike Android, which just requires you to ask for permissions like this when installing the app), I was wondering if anyone had any ideas for other ways to get around this issue. Specifically:
Is it possible to allow the user to pre-approve a specific text message, and delay sending it until the desired time?
Can an external client be used? Ex., ping a server to do the work of sending the text message for the user? This seems like it will get ugly quickly though (since provider info is required), and would require the user to have internet access, not just cell signal. However, perhaps the application can require an initialization text.
The goal here is to send a specific text message for the user when they are unable to do so themselves, so naturally, having them pre-approve the message would be impossible.
You can't send text messages directly from the device.
But I think there is no problem sending them from a webserver, however your app needs to have an internet connection to do this and I am not aware of a service, which allows you to send text messages for free, so you need to pay to provide this service to your users (I can't say if it is ok for Apple to charge your users for such a service). Another drawback of this solution is, that the sender of the text message wouldn't probably be the users number.
I am so confused. My simple requirement is: i have an application which contains confirmation form i.e. nib file. It contains some textFields like name, age, email etc. I simply want when somebody click on submit button application send background and automatic email to email defined in textField. that email contain all information like name, age etc. User need not to fil anything and it should work in background. There are so many application do the same thing. I am creating booking application.
So how can i impliment this behaviour.
Apple does not provide a way to do this - and for good reason. Sending emails from the phone automatically introduces a lot of security risks.
I am willing to bet that the apps that do this use an intermediary server to which they post the data. When the data is posted then the server handles the sending of the emails.
To do this:
Send an HTTPS POST request to your server application.
From your server application, send an email via SMTP (or APIs built on top of SMTP).
Google AppEngine provides a simple and cheap way to create such a web service, running on top of Google's cloud-computing infrastructure. The sending mail from AppEngine help document includes detailed examples of how to send mail from your server application (assuming you use the Python version of Google AppEngine).
Unfortunately, there is no official feature for this but you could download a third-party library. Refer here for a couple of suggestions.
Does anyone know of a free, anonymous smtp service? I want to give users of my app the ability to occasionally send me an anon email without having to configure a server of enter their email account. I guess I could setup a gmail account for this purpose and embed the credentials in the app but I hope it won't be necessary. In case it sways your answer, this is a thick client (.NET Console) app.
I think that what you're asking for is called an open relay.
If there were such a thing, wouldn't it immediately be swamped by spammers?
You might be better off setting up some kind of commenting tool on your website, that sends you an email with the contents of whatever form the user submits. Then if you go that far, it shouldn't be difficult to add a form to your app that automatically makes the full HTTP request (transparent to the user, in the background).
If you run your own mail server, you can simply configure the app to deliver mail directly to it. Many web hosting companies also provide mail hosting if you don't want to run it on your own hardware. Gmail via Google Apps for your domain might be an option. It's free. But their anti-spam measures might prevent delivery. Better to have a server you can control, I think. Bottom line, though, is you don't need an anonymous SMTP relay server to get the job done.
I have a program that, for the most part, operates in the background. Let's say it DoesWork(). Once a week, I want it to notify the user on some of the work it has completed over the past few days. It will be a basic status report, listing some files that have been downloaded.
Initially, I wanted to sent this status update via email, so I looked into that but there are a lot of problems. I need an SMTP server so I looked at GMail. It's okay but has a daily limit of 500 emails, so this wouldn't be suitable for release. Also, there would be issues with the same email account password being given out in each copy of the program, which as I understand it, is a risk even if the password is stored using encryption.
Then I thought maybe I could use the user's own email account to send email to his/her self. This has a couple of complications too: the user would need to specify all of the smtp information for his/her email account, which is too complicated for the target user. Also, I don't want to have to have people entering their email account password into my program just to send emails. I don't think that's a good habit to promote.
Is there any way I could do this via email? Email was my first choice because it's a system of notification that users will already be checking. It's fairly non-intrusive.
Is it necessary to setup my own smtp server? If so, how can I do that?
If email is a no-go, I was also thinking about just generating a local HTML file with the relevent information, and then having a notification popup from the program once a week to inform the user that a new update report is ready. I think this is totally doable, it's just overly instrusive and not my first choice. I want to piggyback on a system that the user is already using.
Thanks!

An alternative is to have the program generate an RSS feed and direct the user how to subscribe to it. Also, once a new update is generated, show the update toast for about a minute, then hide it automatically and change your systray icon to something different. In about a day change it back to the original icon. Also, give the user a setting to turn the toast off permanently.
Relying on email is not a good idea, as you would have to collect the user emails and deal with the privacy issues for that, you would be effectively DOSing any third party SMTP server or would have to invest in the infrastructure for your own.
If I've understood it correctly, the user is running this program on his pc, in the background.
The perfect way to notify something would be, IMHO, giving the program is minimized to the traybar, a small popup that clicked, would open a window with a weekly report.
Hope this helps.
If you do get them to specify their own smtp server, make sure you put a "Send Test Email" button on there so they can test it. I know from experience that users always enter the wrong details when specifying a smtp server, user name, password, which is made worse since some smtp servers require a user name/password and others don't.
If they do enter the wrong details (or they change) then you might need to have some way to send them older reports, or to have some other way of notifying them that you can't send email.
Email's great, but you might need an alternative method also.
Google for simple smtp server windows gives you this
To be honest if you are just sending things once a week email is your best bet, as it's not frequent enough to garantee that the user will be at his machine to accept some other sort of request, which would require you to write proprietory software.
You could alternatively post it to an irc channel, or write an MSN bot to message the user, the message would be sent as an offline message if the user was offline.
I'd still go for email, it's tried and tested.
For a simple SMTP server I use hmail. I configure it to accept all SMTP requests from the local machine, regardless of source and destination, and to deny any SMTP requests not coming from teh localhost. This will be fine if you have a centrally located application.
If you want to distribute the app you have a whole different situation; with a lot of ISPs putting restrictions on SMTP traffic your best option would be to allow users to put in their mail account details and then use that to send mail. This will ensure everyone can put in working settings. Then use whatever library or pre-made code exists for yoru language of choice to send an email using those settings.
Does it need to be a weekly digest? Instead, how about using Growl (or equivalent) to notify the user of the tasks being completed in real-time, in the background?
