Validate Email Address Function

[vetteguy69]

Hello,
I am creating a bash script that needs to validate email addresses. It must call a function to validate the address and see if it's on the local system or not. Then it needs to return a value and send a file to that email address provided it's valid.

Any help is greatly appreciated.

I would use a Perl module called Email::Valid for validating email addresses.

[tt]
use Email::Valid;
unless (Email::Valid -> address($email_addr))
{
warn "Not valid Email address\n";
return;
}[/tt]

#!/bin/sh

function validuser() {
name=$1
awk -v xx="$name" ' BEGIN {
FS = OFS = ":"
if (!xx) {
printf "error: could not read name to compare"
exit
}
}
{
if ($1 == xx) {
print "1"
}
}' /etc/passwd
return
}
val=`validuser $1`
if [ "$val" != 1 ] ; then
echo "Error: invalid user."
exit 1 > /dev/null
else
echo "Found user $1"
#/usr/bin/biabam filename [-s subject] recipient
biabam "/home/myfile" -s "testing" $1
fi

you could always check the output of '/lib/sendmail -bv address'

a check for 'local' would probably be safe ... however aliases for other destinations will check as being relayed ...
