Do you have actual requirements for this?
Why does that matter - well look at the links posted and read them for the complexity of validating that an email address is valid in terms of the RFE that defines it.
However, note that despite that such an address might not work at all. Even though it is perfectly valid.
So if your requirements are to only accept email addresses that work then you need something quite a bite more complicated that simply validating that it meets the RFE. And if you don't need an address that actually works then does it matter if it is valid or not?

Email address validation pattern

First off, I'm using JDK 1.4.2_07. What I'm trying to do is validate email addresses with the String.matches(String pattern) function. What I'm having a problem with is coming up with the regex pattern that represents any syntactically valid email address. If someone has a regex pattern that does represent any syntactically valid email address, I would appreciate it if you posted it in a reply to this message. Thanks!

An error occurred during email account validation

Hello everyone
I have a seriously annoying problem with my BB Curve!
I added a language on to my phone using the Desktop Manager which resulted in the phone being backed up and reinstalled (like a reformat but the data wasn’t lost). Ever since then I am unable to access my email account information that I set up on the phone and wasn’t receiving emails (this coincided with the Blackberry blackout). After that I deleted the email account on using the website email account access for blackberry and re-entered my account information, this allowed the emails to come through my phone but I still cant access my email account information.
If I go to Main Menu > Setup > Email Accounts > Internet Mail Account the phone will hang up while trying access information
If I go to Messages > Options > Email Account Management, I get the following information “Unable to open email setup application. Contact your wireless service provider” I have called Vodafone for the past 5 days now but they are of no help.
If I try to edit the account information (like signatures) on the hutch.blackberry.com website, I get the following error “An error occurred during email account validation. Please check your information and try again.”
Has this happened to anyone before? Is there any solution to this problem?
My phone is currently on Software version 6.0 Bundle 2342
Please help!!!
Gwen

I would keep trying, or wait and try again. There could be a server issue which will be resolved.

BB 8520 Error: An error occurred during email account validation

Device info
Your carrier: TMN Portugal
Model info and OS version: 8520 V 5.0.0.822
Hello,
im getting a problem:
I had my email account configured on a BB. Everything was working fine. I changed for a new Blackberry, and when i switched my device on www.tmn.blackberry.com it asked me to validate my accounts. And when i was trying to validate my email [email protected] i got this error: An error occurred during email account validation.
The problem is that all the settings are fine.Username, password and server name.
And the wierd thing is that i have 2 more blackberrys in my company, with a masterphone.pt email working. But when i try to configure another they all give this error now. No one can change their device, or they will lose the email configuration.

Email field validation

Please let me know the email field validation

I made an awesomely good email verification string:
'^[[:alnum:]][[:alnum:]_\-\.]*@([[:alnum:]]([[:alnum:]\-]*[[:alnum:]])?\.)+[[:alpha:]]+$'Try to break it for me :)
-UPDATE 1-
'^[[:alnum:]]([[:alnum:]_\-\.]*[[:alnum:]])?@([[:alnum:]]([[:alnum:]\-]*[[:alnum:]])?\.)+[[:alpha:]]+$'Forgot the last character of the local part has to be alnum :)
Argh, hyphens still break it in the local part.
-UPDATE 2-
'^[[:alnum:]]([-[:alnum:]_\.]*[[:alnum:]])?@([[:alnum:]]([-[:alnum:]]*[[:alnum:]])?\.)+[[:alpha:]]+$'Hah, apparently hyphens can't be escaped from...
You have to put them at the start or end of the list.

Need email format validation code

I m looking for an email format validation code written in J2ME. It should just verify the format, not if the email address exists or not.

Hi there
I would like to use this to validate across multiple addresses... so i tried...
^((\s*\w+([\.-]?\w+)*@\w+([\.-]?\w+)*\.(\w{2}|(com|co.uk|co.in|in|net|org|edu|int|mil|gov|arpa|biz|aero|name|coop|info|pro|museum)\s*)(;))\s*{1,100}?)?(\s*\w+([\.-]?\w+)*@\w+([\.-]?\w+)*\.(\w{2}|(com|co.uk|co.in|in|net|org|edu|int|mil|gov|arpa|biz|aero|name|coop|info|pro|museum)\s*)(?|;))$
but it doesn't work... it validates against 1 address (with or without a ";" separator... ) but no more...
Any ideas ?

function validateEmail(email) {

Email account validation

I am having problems configuring a specific account to my device. I know the email address works, as it is doing so in Outlook and I have also used the BlackBerry Email Validation Tool which also confirms the same. However everytimne I receive the following message:
"An error occured duruing email account validation. Please check your information and try again."
Thanks in advance.

To answer that part -- you have no direct method to contact RIM (well, not for free at least). Your sole method, as per your contract, is to contact your mobile service provider and, if they need to, they can escalate into RIM at no cost to you. There is no method to, for free, bypass as that is what is required per all contracts covering formal support services for BBs.
Good luck!

EMail Address Validation - Shell Script

Hi,
I have a custom concurrent program (Shell Script Program). One of the input parameter is Email address.
In my code, I need to validate email address format (Ex: [email protected])
Can anyone paste the code snippet.
I have tried with the below validation
case $EMAIL_ID in
*@?*.?*) echo "Email Address Validated.";;
*) echo "Invalid Email Address. Please enter the correct format of email address and re-run the program";
exit 1;;
esac
This validation is failing in this scenario xxx,[email protected] / xxx [email protected] (If user enters the email address with comma or a blank space. This validation is returning success message)
Regards
BS

Please look up the syntax for this by typing
man mailx
on the shell command prompt.

This does not validate .museum tld's, nor email addresses with RFC822/5322 valid characters like ~, #, & and so on.
With other words, come up with better suggestions, kid.

Email address validation, is there a way to use Regex or other fuzzy searching?

I would like to use PL/SQL for Email address validation, is there a way to use Regex (regular expressions) or some other fuzzy searching for that? Using % and _ wildcards only take you so far...
I need something that will verify alphanumeric charectors (no ",'.:#@&*^ etc.) any ideas?
Current code:
if email not like '_%@_%.__%' or email like '%@%@%' or email like '% %' or email like '%"%' or email like '%''%' or email like '%
%' then
The last line is to make sure there are no linebreaks in the middle of the email address, is there a better way to signify a line break, like \n or an ascii equivilent?

Michael:
The as noted in the previous post, DBI is a Perl package that allows Perl to talk to various databases, including Oracle. We use DBI on several UNIX servers, and it does not require ODBC, and I have always found it to be extremely quick. Things may be different in the Windows world.
If you are spooling files out to run through Perl anyway, you may want to take a look at DBI. You could probably modify your existing scripts to use DBI fairly easily. The basic structure using DBI is like:
use DBI;
my dbh;       # A database handle
my sth;       # A statment handle
my sqlstr;    # SQL statement
my db_vars;   # Variables for your db columns
# Connect to the database
$dbh = DBI->connect( "dbi:Oracle:service_name","user/password");
$sqlstr = 'SELECT * FROM emp WHERE id = ?' # even takes bind variables
#Prepare statement
$sth = $dbh->prepare($sqlstr);
$sth->execute(12345); # Execute with values for bind if desired
# Walk the "cursor"
while (($db_vars) = $sth->fetchrow_array()) {

BP Email Address validation

Hi,
Is there anyway to turn off email address validation which occurs when creating Business partner.
For example, abc.com@acb is an invalid email id and the system doesnt allow to save BP. But i want to save the BP even though email id is invalid.
Thanks,
Karthik.

Email form validation

Having trouble with an email form validation. I have an email
field that is optional. Therefore, if the user leaves it blank, the
form should submit. However, I also want to check that if the user
did fill out the email address, it is valid. I am checking that if
it does not contain and '@', a '.' or does contain a ',' to give an
error. Whenever I submit a blank form, it keeps giving error that
the email address is not valid. Here is my code:
<cfif (Len(Trim(form.email)) IS 0)>
<cfif form.email does not contain "@" or form.email does
not contain "." or form.email contains ",">
<script language="JavaScript">
alert("Your email address is not valid. Please correct it
and resubmit the form.")
history.back()
</script>
<cfabort>
</cfif>
</cfif>
Please assist. Thanks, Lumpia.

Pattern for email attribute validation.

I generated an schema for a web service which includes an email attribute, for which I developed a pattern to filter invalid emails but I'm getting facet errors during the schema object creation. My schema works perfectly well in XMLSpy but Oracle's XML parser/schema object fails.
the pattern I am using is:
"([a-zA-Z0-9_\\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)"
which includes some OR logic and nested patterns to validate the email.
I was able to track that using something like (([a-zA-Z0-9\-]+\.)+)) would not be correctly validated in Oracle's XML parser and that \. will cause the schema object creation to fail with facet errors.
I do not know if this is related to the current implementation of the validating parser or something else but I cannot find information on the current implementation that oracle supports (besides a version number). Where can I find information on this... does anyone happen to have a pattern which will validate email addresses and work under oracle parser?
Thanks,
Fedro

Yes, this may related to our implementation for the regular expressions.
Would you send me a simple test case at [email protected] If this is bug, we will fix it.
Thanks.
