I can send email from my gmail account by ssmtp in Linux now. But how can I attach files to the email?

To send an attachment, you need to encode the message using MIME.

You could use Mutt

mutt -s SUBJECT -a ATTACHMENT_FILE_1 ATTACHMENT_FILE_2 -- EMAIL_ADDRESS < MESSAGE_FILE

or mpack

mpack -s SUBJECT -D MESSAGE_FILE ATTACHMENT_FILE EMAIL_ADDRESS

  • Thanks. So is that to say that it is NOT possible to send an attachment by ssmtp alone? – deepsky Jul 26 '12 at 15:26

    It's possible, but you'd have to generate all the MIME headers somehow. Why do you need to only use ssmtp? If ssmtp provides /usr/lib/sendmail or /usr/sbin/sendmail, any local mail program should be able to send via ssmtp. – Mikel Jul 26 '12 at 15:34

    @deepsky ssmtp is not a user interface. It's an MTA (mail transport agent), which is infrastructure meant to be accessed via an MUA (mail user agent, also known as a "mailreader"). It's sort of impressive that you were able to wrangle ssmtp by yourself without an MUA, but it's not a reasonable method of doing things. It's a good network-debugging skill you've learned though! – Alan Curry Jul 27 '12 at 4:47

echo -e "to: receiver@domain.tld\nsubject: subject\n"| (cat - && uuencode /path/to/attachment attachment.name) | ssmtp receiver@gmail.com

This solution does not depend on mutt.

    By the way, SSMTP is used by many people to send automated E-mails through Gmail: nixtutor.com/linux/send-mail-with-gmail-and-ssmtp – metrix Sep 16 '13 at 15:23

$ echo -e "to: receiver@domain.tld\nsubject: test\n"| (cat - && uuencode /path/to/file file.name) | ssmtp sender@gmail.com

Provided that SSMTP is configured, and you've verified that messages without attachments are reaching their destination and does not depend on mutt.
