UNIX mail blank in the TO address

UNIX for Advanced & Expert Users

Hi All,

Can we send a mail in unix blank in TO address with CC and BCC.
TO address should be blank
CC should not be blank
BCC should not be blank

thanks,

Use sendmail, specify just CC & BCC:

{
        print "CC: user@domain.com"
        print "BCC: user@domain.com"
        print "Subject: Testing CC & BCC"
        print "Testing CC & BCC"
} | /usr/sbin/sendmail -t

I am using the below function and parameters
Here $c is TO address and $d is CC. But whenever ther is null in $c it is taking $d as in TO address.
My requirement is if there is null in $c then there should be no one in TO address and $d should be in CC.

notify_users_Weekly $UNEXPENSED_EMAIL_WEEKLY_SUBJ $BASE_UNEXPENSED_LIST_DIR_WEEKLY/User_Email_Msg_30.txt $c $d

Can you post what exactly you are doing inside this function?

function notify_users_Weekly
{
subject=$1
contents=$2
address=$3
CCaddress=$4
 
mailx -s """$subject""" """$address""" -c """$CCaddress"""< $contents >> RC=$?
return $RC
}

Please use code tags for posting code fragments or data samples.

I guess in mailx, primary recipient address is not an optional argument. You do have to specify it.

So why don't you use sendmail instead which can deliver email without a primary recipient?

Yoda is right. Try something more basic than mailx .
Perhaps mail is more basic.
But if your system has sendmail , go for it!
More customized for your needs

echo "\
Subject: $subject
Cc: $CCaddress

$contents
" | sendmail $address

NB: there must be an empty line between mail header and mail body.
The sendmail program might hide in /usr/lib/
And if you want a To: line, just add it to the mail header!
mailx and perhaps mail automatically place $address (the envelope) in a To: line,

i suppose since you are using command line arguments and assigning it to some other variables and when you do not give any one of the argument on command line the next argument becomes that argument

i.e example if you have to pass 4 arguments and if you specify only three then

i.e if suppose u pass 1st 2nd and 4th argument on command line then

the ath argument in above will become 3rd

so it would be better if you can introduce a check and let user know that if he doesny want to specify the to address can u ask then to enter a space in quotes

all pls correct me if im wrong
