I currently have this in an old system I'm working on:
/^[a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*$/
It's checking for usernames. I've imported a few email address as username, and these accounts cannot be validated.
How can I modify the above to allow for email addresses? Thanks.

You can use /^[a-zA-Z_\x7f-\xff][a-zA-Z0-9_.#\x7f-\xff]*$/ as regular expression then. However, it does not check whether the email address actually exists, and it allows for syntactical invalid email addresses as well.
As basically all depends on what you define as valid email address, see some references:

I am developing google-sheets add-on.
I want to functions that create API-link when you input access-key and secret-key.
I think that GAS Properties realize this, but I'm anxious about security. (Unfortunately, I cannot find solutions of this......)
Can anyone give me some advices??
You can use User Properties instead of Script Properties
User properties refer to
property store that only the current user can access, and only within this script.
This means for an Add-on that every user can read and and those properties are only accessible by the active user.

Im looking to hide a post request name from the user, So they cannot post to a URL.
For example, Im looking for something that will avoid users checking the post request name and sending something to bypass the restrictions to insert into a database.
If the POST request comes from the user's browser, then they can inspect it. There is no way to avoid that.
Your only option is to make the POST request from somewhere else (such as your server). There is a good chance that you won't be able to do that (due to dependencies on the request coming from the user or included data they supply).
You mention "restrictions". If those restrictions are currently enforced with client side code: Enforce them with server side code.

I'm an email marketer. I was ask to create an email where if the client open the mail, the reply window with specific email address will pop. Do you have any idea what can I use/do?
Thanks in advance for your help.
You can't. Email doesn't (thankfully) have a feature that would allow you to do that.
You can have replies go to a different address to the one the mail was sent to with a Reply-To header, but you can't hit the reply button for the user. They get to read the email and decide if they want to reply first.

I have never done anything like this... So here it goes.
I need to be able to submit (at one time) roughly 300 user ids and get back their name and email address... The company has all this info in active directory.
Does anyone have any idea how this would work with Perl, or really any language? I don't even know what type of UI I would need, and how to actually connect to AD to get the requested information..
Any and all help is appreciated!
you can connect to Microsoft AD with Net::LDAP - Lightweight Directory Access Protocol

SCRIPT I USED : http://sourceforge.net/projects/oes/
It uses MySQL's ENCODE and DECODE functions with a salt of oespass. This is, by the way, very bad.
