JavaMail using SMTP to verify email address

hi,
does any samples to verify email address by SMTP using JavaMail ?
Thanks in advance.

I think this is as close as you can get, to validating
an actual e-mail address,
so more info
"Performs a DNS lookup on a domain to find the mail exchanger (MX) record. This can be used as part of an email system, or to validate email domains. E.g. if a user enters [email protected], use the component to get the MX record for hotmail.com. If no MX records are returned, it's not a valid e-mail address. "

    Reset it by holding the power and home buttons at the time until you see the Apple logo (ignore the slide to shut down screen), then release.

  • Icloud will not back up because it says email address not verified.  I am not getting a link in my email to follow to verify account, checked email address listed is correct, so how do I verify email address when I dont get the email link?

    I am unable to verify email address to sign in to icloud so that I can backup my stuff.  I am not getting an email from apple to follow a link to verify email address.  I have checked to make sure the email address is correct in the icloud settings, but all it will tell me is to check my email for instructions on how to verify my account.  I am not getting the email!  Please help, I am able to sign in to my itunes account and buy new music all the time!  I get my itunes receipts and everything, and know the email is correct so what is the deal?

    If you have given correct info about you ios 6.1.3 - all you need to do is delete account. You will be able to sign in with new one afterwards. Make sure you don't delete any info when you see those prompts.

  • Apple has just deleted my alias - which I was using as my main email address.  They deny me creating a new one for 7 days.  How can I get in touch with Apple so that they repair what they have broken?

    Has anyone had a problems with their alias today?
    Apple has deleted mine today; causing me a major headache as they deleted the alias that I use as my main email address.
    What happened exactly, is that the @icloud.com alias remained, but the @me.com disapeared.  So that the John.Smith alias became valid only for [email protected], but [email protected] disapeared.
    To try to restore the situation, I deleted the alias, with the hope of re-creating it: but bad luck, that option is not open to me as I have had 5 aliases active till today, and they now only give you 3, and even once I had deleted 2, they would not allow me to set-up a new one for 7 DAYS.
    I can't be without email for 7DAYS, care of Apple.  Calling AppleCare does not seem to help, and the line gets dropped once I have explained the problem.
    Please help me raise someone at Apple to fix this.

    How do I enable my new device with an existing ID - I do not need to change the password for the millionth time!
    None of the FAQs (or the Community choices below) address new devices, they are all about APPS and iCloud stuff.

    If it is an existing iCloud ID, you should be able to just go to Settings>iCloud and sign in with it.

  • How can I use my old MobileMe email address if I did not migrate to icloud by the deadline?

    I had a mobile me account that I did not migrate to icloud.  Now when I try and set up an icloud account using the old mobileme email address, it says that address is already in use. I then try and access it but the password doesn't work and it says mobileme is closed. When I try and reset the password, it says an email has been sent to the email on file...which is an old mobileme address that I cannot access.
    How can I get this email address set up in icloud? 

    Nice idea - I tried it but it doesn't seem to work (at least not for me).
    So here are the details in case, you can spot something more I could do....
    When MobileMe was live
    MobileMe ID was [email protected]
    AppleID (to make iTunes purchases) was [email protected]
    When iCloud went live (and MM was still alive)
    iCloud account was created based upon AppleID - [email protected]
    iCloud would not create [email protected] as was already in use (by me)
    iCloud would not merge [email protected] as iCloud does not merge
    MobileMe migration to iCloud option was not taken
    Deleted all data out of MobileMe account (mail, calendar, contacts, gallery)
    Deleted MobileMe mail account off of all devices
    When MM died
    I received notification that I had not migrated my MM account
    iCloud was happily working as Contacts/Calendar sharer using my AppleID of [email protected]
    Weeks later on Mac running 10.8
    System Preference - iCloud, already logged in with AppleID of [email protected]
    Then ticked the untick Mail box
    Long wait with small grey whirling cog box, stating "Loading". Eventually a BLANK message box with OK which then disappeared on a timeout.
    System Preference - Mail...  Re-added [email protected] (now picked up as iCloud account)
    Mail - Accounts.... Re-added [email protected] BUT got message "Mail can'y connect to the account..."
    So tried logging into www.icloud.com (using AppleID of [email protected] where my contacts/calendar now reside).  Clicked on Mail icon and received "@me.com Address Needed" message

  • Why can't I use my previous MobileMe email address instead of creating a new one?

    Why can't I use my previous MobileMe email address instead of creating a new one?  When signing up for iCloud I'm asked to choose an email address [email protected]  I am already using an @me address via moblileme.  When i input that address it states that that address is already taken.  Try picking a new one.  I don't want a new one I want to use my mobileme address.  How can that be done?

    It appears you set up a new iCloud account rather than migrating your MobileMe account over to iCloud.  I migrated everything over this morning and am still using my old MobileMe email address.
    Check to see if you can migrate rather than open a new account.

  • I bought pages ages ago using an iTunes account that no longer works as the email address has been closed down. How can I now update my Pages app, if it asks me to sign in using this now defunct email address?

    I bought Pages ages ago using an iTunes account that no longer works as the email address has been closed down. How can I now update my Pages app, if it asks me to sign in using this now defunct email address?

    All apps are always tied to the account from whaich they were purchased and will always have to be updated using that account.
    Just because the e-mail account is shut down, has nothing to do with the itunes account. Why did you create a new account?  Why not just change the e-mail associated with the old account?

  • Why can't I use and in the email address on my iPhone?

    When in email address input mode, on iPhone, the < and > are not available.  These characters are used to indicate an email address when a name is used as well.  For example....   John Smith <[email protected]>   This will add John Smith and his email address to my contact list, not on my phone, but in my email.  Please tell me this will be possible when iOS7 comes out.
    Thanks,
    Eric
    For now, the only way to do this is to go to the body of the email, enter the info    John Smith <[email protected]>   cut and paste it into the email address location.

    Thank you! That worked... I didn't even remember I had that app on the phone .

  • Can you use more than one email address on one account as to enable two or three devices to use imsg????

    Can you use more than one email address on one account as to enable two or three devices to use imsg as when i add new email address's in settings it just says veriyfying and nothing happens????

    If I read your question right, yes.
    My pad has two e mail addresses, and my phone has a phone number as well as a e mail address.  For each device you can add additional 'receive at' addresses in settings.
    Note, when you add a new address, apple will send an e mail to that new address that you need to respond to, to show that it is a valid address.  So look in the inbox of that e mail account for the verification e mail.  Note further, some spam filters think that the verification e mail might be spam, so if it does not show up in your in box, look in any spam file you might have.
    in my case, the verification e mail came within a few minutes of declaring the new address.
    The multiple address are useful if you have more than one device under your apple id, and want to be able to send stuff to that particular device.

    Have you tried a soft-reset ? Press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider if it appears), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

  • Email - request to verify email address - cant get rid of this

    Checked my email (Verizon email) and no email was sent to me for email verification.  Nothing sent to inbox and nothing in my spam folder. It didnt send anything to me.   I am tired of that message popping up and that other one too about the facebook connect or whatever.  It pops up and blocks the inbox message amount.  Stupid.

  • IPad cannot backup without a verified email address--LOCKED

    Message pops up after lock screen that says:
    "iPad cannot backup without a verified email address"
    with the options of LATER and SETTINGS.  I usually select LATER button and move on.  This time it is locked up.  I tried a hard rest by pressing the home button and power/ sleep button but nothing happens. 
    I have not setup an iCloud account, and have not set up to sync with a Mac or PC. 
    Please help. 

    Thanks JimHdk,
    Can't get to the settings due to the error message.  It will not allow me to select an option. 
    I do believe that a hard reset is the answer, and i am able to go through to the black out screen, but the Apple logo is not coming up. 
    If I am unable to accmplish a hard reset today I may just have to make an appointment at the genius bar.
