Kurzbeschreibung des Wettbewerbs
Hello,
I am looking for a function to validate email address in following ways
a) It should check syntactically a valid email address.
b) Validate the domain is a valid one and can receive emails for that domain.
c) Validate the email address exists.
This should be done using SMTP gateway access which require username and password to access the gateway.
It should generate error codes as follows:
wrong_email_address - Which represent syntactically wrong email addresses
wrong_domain. - Which denotes the wrong domain
invalid_address -Email address doesn't exist.
All codes should be properly and thoroughly commented.
This is to be done in PHP. The email address and message should be inserted into a table in mysql DB
Table emails (
email_id varchar(255),
msg varchar(255)
);
Before inserting the email address into the table, check if it is already in the table. If yes, just update latest message. Otherwise insert the new record.
And,, AHAH.... No existing or already available general functions please...
Happy coding.....

Its very doable. But don't you think 10$ a little to less for such a contest/task?

Wanted to see a contest functioning and get a clean code. That was the idea. I have bits and pieces of code addressing these issues. I could make it into a class. However, I thought there could be very good coder who can address this and make clean and concise code. Once the contest is over, if I don't get good code for the function/class, I will include my code here for all to see and use, if needed.

That is correct. It checks the domain. But id doesn't check if the email address really exist.

All entries handles either step 1 and 2. None check for all steps. Hence all entries received till now are rejected.Some have addressed the syntax check (step 1), some addressed the domain check (step 2). However none addressed the checking if the email address really exist.

If the syntax is correct, but the domain is wrong, then no need to check for validity of email address. Validity check calls for interaction with SMTP server.

THis is to avoid detailed step as first source. If the syntax is wrong, no need to go further and check others which will call for network checking.

Why bother doing steps (1) and (2)? If step (3) is successful, it would imply that steps (1) and (2) would have been successful had they been attempted. Or is it actually important to understand at which step a particular address fails?

b) and c) are more or less impossible.

I got some idea about this. Looking for a neat and concise code as a function or class.

OK. I saw the code to validate the correctness of email address and the domain. Hence, it is possible to do it. However it was a patchy work. Want a very tidy Single function for these.
