unix mail utilities mail or mailx can be used to send mails to users within a machine, a remote machine or web users using a relay server.
To end mail to user hradmin on the machine v_serv1
/home/gadm$ mail x –v -s “intimation” hradmin@vserv_1 <mail_content_file
Here the text “intimation”after –s is the subject and mail_content_file contains mail body.
Configurations for sending external mails through a relay server(eg IBM LOTUS) .
1)make an entry of mail relay server in /etc/mail/sendmail.cf file(can be done from root login)
DS<mail relay server name> ->add your mail server hostname in domain form(eg: mailserver.cbbs.net)
2) edit /etc/hosts file and make an entry of mail relay server.
10.5.6.34 <mail_svr_hostname> <domain_name>
Also If your hostname contains only IP and plain hostname like
Add another column to make your hostname have a valid domain name(eg .com) otherwise you will get “hostname not qualified” error.
10.234.45.56 <my_hostname> <my_hostname@<my_domain>
Ask your mail admin to add this hostname as a qualified hostname for receiving mails from.
3) stop and start the sendmail daemon.
stopsrc -s sendmail
startsrc -s sendmail -a “-bd -q30m”
Now you can send external mails using mailx command as follows.(AIX)
mailx -v -s “<subject>” -r “< sender_name>” -c ”<cc_address(es)>” <to_address> < content_attach
“<subject> “ Is a quoted text received under subject(quoting is must when there is space in the text.
<sender_name> Is the name of the sender as seen by the recipient. If it is not used the recipient will see the sender as your <default firstname.lastname@example.org>.
”<cc_address(es)> Refer to those addresses to whom you need to send the copies of this mail to.
“<to_address> “ Actual recipient address.
content_attach A file containing body of the mail and encoded attachments.
A file like conetent_attach can be formed by using the uuencode command. For example if you hava a content file named c_mail_body.txt and an attachment /home/v_admin/pdf_archive/trans_list.pdf file to send .
Uuencode /home/v_admin/pdf_archive/trans_list.pdf trans_list.pdf >> c_mail_body.txt
Now the file c_mail_body.txt will contain both mail contents and attachment. You can use this file to input as content_attach file in the mailx syntax.
mailx -v -s “<subject>” -r “< sender_name>” -c ”<cc_address(es)>” <to_address> < c_mail_body.txt
