TARGET_EMAIL question

[middleburyman]

I'm using exact e-mail addresses in this area.
First question: Is there a limit to the number of e-mail addresses you can put in this area of the script and/or form? I have about 100.
Second question: Do I have to put each individual address in both the formmail.php file and the form file? I assume so.
Third question: Some of the e-mail addresses I'm using have more than one 'dot' after the 'at' symbol. Example: me.co.zw or public.lib.in.us. Do I need to use the '\' symbol after each dot or just after the one after the 'at' symbol? Which is right and/or more secure?

me@public\.lib.in.us or me@public\.lib\.in\.us

Let me know. Thanks.

Hi,

First question: Is there a limit to the number of e-mail addresses you can put in this area of the script and/or form? I have about 100

No limit (other than the finite resources of your computer ). 100 or more will be fine.

Second question: Do I have to put each individual address in both the formmail.php file and the form file? I assume so.

Yes. But if you have several from the same domain, and, that domain isn't a general one like "msn.com" or "yahoo.com", you can use the EMAIL_NAME feature as shown to match a number of addresses in one entry in $TARGET_EMAIL.

Like this:

 $TARGET_EMAIL = array(EMAIL_NAME."@rootsoftware\.com$", // millions of addresses at rootsoftware.com
                "^jacksprat@rootsoftware\.com\.au$", // exactly one address
                EMAIL_NAME."@ttmaker\.com$",    // millions
                "^john\.smith@timetabling\.org$",  // exactly one
 ); 

Third question: Some of the e-mail addresses I'm using have more than one 'dot' after the 'at' symbol.

Put a backslash before each dot anywhere in the email address. It's really not critical but it is more secure.

Here's the explanation....

In a pattern (regular expression), "." matches any character, whereas "\." matches only a literal ".". So, this pattern:

 
  john.smith

will match "johnasmith", "johnbsmith", ..., as well as "john.smith"

Whereas this pattern:

 
  john\.smith

will only match "john.smith".
