Question

I want to remove special characters from the starting of the string only.
i.e, if my string is like {[e-mail] then I want to remove the { from the starting. The string shoould look like [e-mail]

But if my string is like abc{@xyz.com then I want to retain the same string as it is ie., abc{@xyz.com.

Also I want to check that if my string has @ symbol present or not. If it is present then OK else show a message.

The following demonstrates what you specified (or it’s close):

var pat = /^[^a-z0-9]*([a-z0-9].*?@.*?$)/i; //pattern for optional non-alphabetic start followed by alphabetic, followed by '@' somewhere
var testString = "{[e-mail]"; //Try with {abcxyz.com for alert
arr = pat.exec(testString);
var adjustedString;
if (arr != null) { adjustedString = arr[1]; }  //The potentially adjustedString (chopped off non-alphabetic start) will be in capture group 1
else { adjustedString = "";  alert(testString + " does not conform to pattern"); }
adjustedString;
