How can I send attachment with ssmtp in Linux?

Question

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

swaks : https://jetmore.org/john/code/swaks/faq.html#send_html_email should do the trick, and is built for automation as that seems to be your goal. — Nicholas Saunders, Dec 19 '23 at 13:50

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: http://www.nixtutor.com/linux/send-mail-with-gmail-and-ssmtp/ – metrix Sep 16 '13 at 15:23

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 04:47

$ 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.

another alternative to uuencode is to use base64 commend instead ->

cat msg_source.txt | (cat - base64 && attachment.bin) | ssmtp -vvvv email@domain.com

where msg_source.txt contains header tags, like To:, From:, Subject:, Content-Type:, etc
