I've been searching for the best way to send an e-mail with an attachment by my java application. I want to use this as an users bug report with logger files. The recipient should be my own e-mail address. I'd prefer the use of an e-mail client.
I tried the following:
Send an e-mail with user authentification like this. I don't want to use this, because the user would need to reveal his e-mail account and password. Furthermore, I'd have to set the properties for every e-mail adress, which is impossible.
Send an e-mail directly to my own e-mail address like this in Listing 16.16 (didnt found an english example). The problem is every e-mail server is using POP authentification nowadays, that means the recipient e-mail server won't accept my e-mail.
Using the mailto URL syntax like this. Doesn't work aswell, because the attachment function isn't working properly in every e-mail client. Best solution so far is to brief the user to add the attachment by himself, after I would put it to his desktop. Or upload the data and add a link to the e-mail body.
The last way I've found is this one. As you could assume this won't work either, because the localhost needs to be connected to the internet and capable enough to send an e-mail.
Hopefully I explained my problem well enough. Is there a different way to send bug reports?
The generally accepted way to get around the problems you describe is to keep all the email logic server side, and then have your application call a web service with the appropriate parameters. It's pretty easy to knock a PHP script / servlet up that will do the job and then send the results on via email, put them in a mysql database or so on.
However, if you can't / don't want to / won't keep this server side, I'd recommend using JavaMail to create a MimeMessage, then using writeTo() to write this to an EML file.
You can then do the usual:
Desktop.getDesktop().open(emlFile);
...which will open the EML file with the default application for handing those files, which is almost always the mail client. Still not foolproof, but if you're determined on sending the email from the client directly I think that's as good as you'll get.

I want the email to be sent immediately, currently the application is showing me installed email applications in device where I can recompose the email before sending, I want to send the mail directly without showing installed applications.
I Know javamail but need email .. other user can decompiler app and theft email :)
The way to go is to send the mail via some server, not directly from the device. You would, for example, connect to a REST API that sends out the email for you. Sending an email directly from the device from the user's email address is not (and should not be) possible
There are two ways to send email from android application directly without any intent
using SMTP & JavaMail API follow the link for details
using Webservice( for example PHP script ) so there is a server side code and you hit that URL with param like ( name,subject etc) so basically PHP code send mail at the end and it's very easy to use .
Personally, I suggest you use Webservice because it's simpler than first approach.
** Edit: You can save email in sharedpreferences or database and fetch it from there when you try to send mail rather than hardcoding it to avoid theft email risk.(directly putting mail address inside code)
Anyway you can prevent other from getting your full source code.See this answer
In my java project project I like to send a mail to group or to an individual user. I want to know whether the mail has to be delivered or not for sender. If the mail address will be wrong then go to the report.
There is no standard way of doing this that's accepted and honored across the board. I see that you have some options, though:
Add a header "Return-Receipt-To" with your e-mail address in the value. If the recipient of the e-mail has a client which honors this header, then a return receipt will be sent to you when the e-mail is opened. This is not reliable, mind you, as the user can always decide not to send the receipt, even if he has a client that supports it.
Add an image into your e-mail that loads from your server and put a parameter on the image that includes the user's e-mail address. When the e-mail loads, the image will load from your server. Write a script that collects the e-mail parameter and then delivers a blank image. This is also not reliable, however, as many mail clients prompt users if they wish to download images and they can always choose not to. Also, some (mostly older) e-mail clients do not support images.
Perhaps the most reliable way is not to include the message in your e-mail at all. Include only a link to a website where the message can be read, and include their e-mail address or a unique code in the link. This way, you know exactly who read the message. Of course, this has the downside that people aren't actually getting the message in their inbox, and they also may choose not to go to the website to read it.
Ultimately, I think you're going to have to come up with a creative solution to solve this problem, unless you're happy getting spotty results.

Perhaps this kind of question comes under not to ask category but for the sake of application I have to ask.So pardon me.
At the time of Log in,I found that(suppose)If I am unable to remember my password,then I have to put my email-id then an auto generated reply come from that's hosted site with
a new link for generating another new password or
simply sending password(that means password isn't encrypted,I guess) in reply.
watching the source code it's hard to predict,but I want to know(if they are using jsp) then which protocol is used for this auto generated mail what are the other things to remember to achive this, while I'm also making an application for auto generated mail.
I have done this using javax.mail api in java
google for sending mail using java...
define content of mail in template or resource file and send mail whenever user clicks on forgot password link.
It is using SMTP protocol only.
I want to be able to send an email to an email address, and then have it appear on a web page. Is this possible?
My guess is you'd have to write your own email server, something which I am not capable of doing. So I am assuming this won't be possible for me.
But if there is some way it can be done, that would be great. I generally program in Java and use Tomcat as my app server.
No, you wouldn't have to run your own SMTP server. You'd simply need to be able to retrieve mail from a POP3 or IMAP server, using something like the mail client API found in javax.mail.
It would be up to you to decide how much control you'd give to users. For example, who specifies the IMAP settings? Who decides which messages to fetch and display? Maybe that's all pre-configured. Maybe you write full-featured, web-based email client that can send messages as well as retrieve. This is all determined through the design of your web application.
You don't need to write your own mail server. You can use an ordinary (external) mail server and poll its inbox via POP3 or IMAP from your software. This introduces a short delay up to the full poll interval, but that might or might not be acceptable for you.
I can't give you a good tip for a email client lib to use for that, though.
Here is a simple example of sending email trough Google's SMTP server.
I have designed a chat application where different users can create the account, but I do not know how to send a confirmation email to the users. Since I collect their e-mail address in the registration form, how can I send mail to those addresses in Java?
First of all, you need a SMTP server. It's required to be able to send emails. You can make use of the SMTP server associated with your own existing email account, such as the one from your ISP or public mailboxes like Gmail, Yahoo, etc. You can find SMTP connection details at their documentation. You usually just need to know the hostname and the port number. The login details are just the same as from your email account.
You're however restricted to using your own address in the From field of the email and usually also in the amount of emails you're allowed to send at certain intervals. If you'd like to get around this, then you need to install your own SMTP server, for example Apache James, which is Java based, or Microsoft Exchange and so on.
Then, to send an email using Java code, you would need the JavaMail API or the more convenienced Apache Commons Email.

Google 'send mail java'
The easiest way of doing this really depends on the environment that your JVM is running in.
If you're running in a standard Linux/UNIX environment and don't want to faff about with extra libraries, then one way is just to "manually" call sendmail (e.g. via ProcessBuilder). As with executing commands generally, you just need to be slightly careful that you don't just pass user input as parameters without screening them.
