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

I'm creating a website(say somesite.com) in Java. A part of the website is: users are provided with e-mail address (username#somesite.com)
and can send & receive emails using the e-mail address and the website.
Now, the problem is to setup a mail server. I tried hMailServer but hMailServer uses its own database tables which is very difficult to
use with the website database design.
Is there anyway to use mail server but store those emails in the way I want
(in website database tables)?
I don't know if this reach your expectation, but take a look at Apache James:

I have developed an app with a login. To help users I would like to send a mail reminding their credentials.. 2 solutions but 2 problems:
1) If I send the mail from the mobile phone (using my gmail account and mail.jar library) Google always reports a possible violation of my account or a suspect access, blocking it. I read several forum page about remove this feature but some people say that Gmail is built to be used by a single person
2) If I send a mail from a php page (using the function mail($mailto,$subject,$message,$header) several mail server put automatically this email into the trash folder.
Any suggestion? How to solve this issue?
Thank you in advance
You could send mail in java (mail.jar or mailServices of Spring Framework). I suggest you to use a mail provider service to send mail. It's better because there many things to care with when you send email ( email does not exist, delay of receiving the email, the current status of email sent, received or read...)
i have requirement that i need to send/receive email after successful login by user, upon click on email verification i will activate the user . i dont have dedicated smtp server for send/receive mails for this requirement. right now i am looking for free service for initial start up options , i gone through this http://www.mkyong.com/java/javamail-api-sending-email-via-gmail-smtp-example/ for sending email through gmail. my question is can i receive mail using gmail smtp service?
Short answer: No, not with SMTP. But probably with IMAP/POP.
Long answer: SMTP is only used for sending email between MTAs (Mail Transfer Agent). You'll have to download the email from your email provider, google in this case, using IMAP or POP.
You'll have to connect and check regularly as without an MTA service on your end, you can't get email pushed to you. Most personal ISPs block outbound port 25 so setting up a MTA might be tricky as you have to figure out your providers SMTP relay (if they even have one!)
See here for enabling IMAP/POP support for gmail:

Google will find you a suitable imap/pop client library to use with java.
Edit:
If you are doing a regular e-mail verification step for a website registration, you don't need to receive an e-mail from the user. You send them an e-mail with a a link to your websites verification URL. The link contains a predetermined ID, say the sha1 sum of username + e-mail encoded into the URL. The user clicks the link and opens a specific page on your site where you verify the ID when the page is loaded. This is how it is usually done. This way you don't need to receive any email programmatically.
Unless receiving it by email is a specific requirement from your customer, in which case you can ignore this edit. :)
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 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.
