Question

How can i send an email through UNIX mailx command

Answer 1

mail [-s subject] [-c ccaddress] [-b bccaddress] toaddress

-c and -b are optional.

-s : Specify subject;if subject contains spaces, use quotes.

-c : Send carbon copies to list of users seperated by comma.

-b : Send blind carbon copies to list of users seperated by comma.

Hope my answer clarifies your doubt.

Answer 2

Here is a multifunctional function to tackle mail sending with several attachments:

enviaremail() {
values=$(echo "$@" | tr -d '\n')
listargs=()
listargs+=($values)
heirloom-mailx $( attachment=""
for (( a = 5; a < ${#listargs[@]}; a++ )); do
attachment=$(echo "-a ${listargs[a]} ")
echo "${attachment}"
done) -v -s "${titulo}" \
-S smtp-use-starttls \
-S ssl-verify=ignore \
-S smtp-auth=login \
-S smtp=smtp://$1 \
-S from="${2}" \
-S smtp-auth-user=$3 \
-S smtp-auth-password=$4 \
-S ssl-verify=ignore \
$5 < ${cuerpo}
}

function call: enviaremail "smtp.mailserver:port" "from_address" "authuser" "'pass'" "destination" "list of attachments separated by space"

Note: Remove the double quotes in the call

In addition please remember to define externally the $titulo (subject) and $cuerpo (body) of the email prior to using the function

From the man page:

Sending mail

To send a message to one or more people, mailx can be invoked with arguments which are the names of people to whom the mail will be sent. The user is then expected to type in his message, followed by an ‘control-D’ at the beginning of a line.

In other words, mailx reads the content to send from standard input and can be redirected to like normal. E.g.:

ls -l $HOME | mailx -s "The content of my home directory" [e-mail]

Answer 4

echo "Sending emails ..."
NOW=$(date +"%F %H:%M")
echo $NOW  " Running service" >> open_files.log
header=`echo "Service Restarting: " $NOW`


mail -s "$header" [e-mail],   \
              [e-mail], \ < open_files.log

Answer 5

If you want to send more than two person or DL :

echo "Message Body" | mailx -s "Message Title" -r [e-mail] [e-mail],receiver_dl@.com

here:

• -s = subject or mail title
• -r = sender mail or DL

Answer 6

an example

$ echo "something" | mailx -s "subject" [e-mail]

to send attachment

$ uuencode file file | mailx -s "subject" [e-mail]

and to send attachment AND write the message body

$ (echo "something\n" ; uuencode file file) | mailx -s "subject" [e-mail]
