Here is inline:

Code:
A=("one" "two" "mail@yourhost.com")
B=("one" "two" "three")

for((i=0;i<${#A};i++)) {
   if [[ ${A[i]} = *@* ]]
   then
       echo "A contains @"
   fi
}

for((i=0;i<${#B};i++)) {
   if [[ ${B[i]} = *@* ]]
   then
       echo "B contains @"
   fi
}


And here is function version:

Code:
A=("one" "two" "mail@yourhost.com")
B=("one" "two" "three")

containsAT() {
    for((i=1;i<=$#;i++)) {
        [[ "${!i}" = *@* ]] && return 0
    }
    return 1
}

if containsAT "${A[@]}"
then
   echo "A contains @"
fi

if containsAT "${B[@]}"
then
   echo "B contains @"
fi

NAME
rbash - restricted bash, see bash(1) RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow- ing are disallowed or not performed: o changing directories with cd o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV o specifying command names containing / o specifying a file name containing a / as an argument to the . builtin command o specifying a filename containing a slash as an argument to the -p option to the hash builtin command o importing function definitions from the shell environment at startup o parsing the value of SHELLOPTS from the shell environment at startup o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators o using the exec builtin command to replace the shell with another command o adding or deleting builtin commands with the -f and -d options to the enable builtin command o using the enable builtin command to enable disabled shell builtins o specifying the -p option to the command builtin command o turning off restricted mode with set +r or set +o restricted. These restrictions are enforced after any startup files are read. When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script. SEE ALSO
