Question

我想将HTML文件作为邮件正文发送，并希望将多个文本文件附加到此电子邮件中。

由于需要发送html文件，因此必须使用sendmail（我无法使用mailx）。

如何使用sendmail发送HTML正文电子邮件和多个文本附件？

Answer 1

假设您的系统中有可用的uunecode，您可以发送包含多个附件的电子邮件，如下所示：

#!/bin/bash

...
...
...
BOUNDARY="=== This is the boundary between parts of the message. ==="

{
   echo  "From: $MAILFROM"
   echo  "To: $MAILTO"
   echo  "Subject:" $SUBJECT
   echo  "MIME-Version: 1.0"
   echo  "Content-Type: MULTIPART/MIXED; "
   echo  "    BOUNDARY="\"$BOUNDARY\"
   echo
   echo  "        This message is in MIME format.  But if you can see this,"
   echo  "        you aren't using a MIME aware mail program.  You shouldn't "
   echo  "        have too many problems because this message is entirely in"
   echo  "        ASCII and is designed to be somewhat readable with old "
   echo  "        mail software."
   echo
   echo  "--${BOUNDARY}"
   echo  "Content-Type: TEXT/PLAIN; charset=US-ASCII"
   echo
   echo  "This email comes with multiple attachments."
   echo
   echo
   echo  "--${BOUNDARY}"
   echo  "Content-Type: application/zip; charset=US-ASCII; name="${ZIPFILE}
   echo  "Content-Disposition: attachment;   filename="`basename ${ZIPFILE}`
   echo
   uuencode $ZIPFILE $ZIPFILE
   echo
   echo  "--${BOUNDARY}--"
   echo  "Content-Type: application/pdf; charset=US-ASCII; name="${PDFFILE}
   echo  "Content-Disposition: attachment;   filename="`basename ${PDFFILE}`
   echo  
   uuencode $PDFFILE $PDFFILE
   echo
   echo  "--${BOUNDARY}--"
} | /usr/lib/sendmail -t

Answer 2

我认为sendmail不会帮助你。转到类似mutt的客户端，例如mutt -a file1 -a file2 -- recipient@do.main。或者去perl。

Answer 3

这是一个bash脚本，用于向人们发送我生成的报告。它们作为附件发送。将HTML放在脚本的“body”变量中。我将把变量的参数化留给你。

#!/bin/bash

function get_mimetype(){
file --mime-type "$1" | sed 's/.*: //'
}

from="me.last@company.com"
to="some.one@companyBlah.com"
subject="Your Report my Lord"
boundary="=== Boundary ==="
body="The reports are attached to this email"
declare -a attachments
attachments=( "fileOne.out" "fileTwo.out" "fileThree.out" "file-et-cetera.out")

# Build headers
{

printf '%s\n' "From: $from
To: $to
Subject: $subject
Mime-Version: 1.0
Content-Type: multipart/mixed; boundary=\"$boundary\"

--${boundary}
Content-Type: text/plain; charset=\"US-ASCII\"
Content-Transfer-Encoding: 7bit
Content-Disposition: inline

$body
"

for file in "${attachments[@]}"; do

      [ ! -f "$file" ] && echo "Attachment $file not found, omitting file" >&2 && continue

        mimetype=$(get_mimetype "$file")

  printf '%s\n' "--${boundary}
Content-Type: $mimetype
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename=\"$file\"
  "

  base64 "$file"
  echo
done

# print last boundary with closing --
printf '%s\n' "--${boundary}--"

} | sendmail -t -oi
