將 sendmail 用於 HTML 正文和二進制附件

Question

目標：發送帶有 HTML 正文和二進制附件的郵件（使用 sendmail）。

遵循以下鏈接中指定的准則

http://www.unix.com/shell-programming-scripting/159522-sendmail-html-body-attachment-2.html

http://www.unix.com/shell-programming-scripting/58448-sendmail-attachment.html

它的工作范圍是，HTML 正文或帶有 uuencode 的二進制附件，但不能兩者兼而有之。

下面給出了發送郵件的 shell 腳本片段。 有了這個，HTML 正文就可以正常工作了，但是附件編碼/解碼錯誤，無法查看。

請指教。

#!/usr/bin/ksh

export MAILFROM="noreply@site.dom"
export MAILTO="somebody@somesite.com"
export SUBJECT="Test PDF for Email"
export BODY="email_body.htm"
export ATTACH="file.pdf"
export MAILPART=`uuidgen` ## Generates Unique ID
(
 echo "From: $MAILFROM"
 echo "To: $MAILTO"
 echo "Subject: $SUBJECT"
 echo "MIME-Version: 1.0"
 echo "Content-Type: multipart/mixed; boundary=\"-$MAILPART\""
 echo "---$MAILPART"
 echo "Content-Type: text/html"
 echo "Content-Disposition: inline"
 cat $BODY
 echo "---$MAILPART"
 echo 'Content-Type: application/pdf; name="'$(basename $ATTACH)'"'
 echo "Content-Transfer-Encoding: base64"
 echo 'Content-Disposition: attachment; filename="'$(basename $ATTACH)'"'
 uuencode -m $ATTACH $(basename $ATTACH)
 echo "---$MAILPART--"
) | /usr/sbin/sendmail $MAILTO

我正在使用 HP-UX ia64。 在論壇和網絡上進行了搜索，發現主要是對 PHP、Python 等的引用。

Answer 1

將電子郵件中的內容傳輸編碼類型從 base64 更改為 uuencode 解決了該問題。 感謝您到目前為止的投入。

下面給出的是修改后的有效腳本。

#!/usr/bin/ksh

export MAILFROM="noreply@domain.com"
export MAILTO="mail.to@gmail.com"
export SUBJECT="Test PDF for Email"
export BODY="email_body.htm"
export ATTACH="file.pdf"
export MAILPART=`uuidgen` ## Generates Unique ID
export MAILPART_BODY=`uuidgen` ## Generates Unique ID

(
 echo "From: $MAILFROM"
 echo "To: $MAILTO"
 echo "Subject: $SUBJECT"
 echo "MIME-Version: 1.0"
 echo "Content-Type: multipart/mixed; boundary=\"$MAILPART\""
 echo ""
 echo "--$MAILPART"
 echo "Content-Type: multipart/alternative; boundary=\"$MAILPART_BODY\""
 echo ""
 echo "--$MAILPART_BODY"
 echo "Content-Type: text/plain; charset=ISO-8859-1"
 echo "You need to enable HTML option for email"
 echo "--$MAILPART_BODY"
 echo "Content-Type: text/html; charset=ISO-8859-1"
 echo "Content-Disposition: inline"
 cat $BODY
 echo "--$MAILPART_BODY--"

 echo "--$MAILPART"
 echo 'Content-Type: application/pdf; name="'$(basename $ATTACH)'"'
 echo "Content-Transfer-Encoding: uuencode"
 echo 'Content-Disposition: attachment; filename="'$(basename $ATTACH)'"'
 echo ""
 #uuencode -m $ATTACH $(basename $ATTACH)
 uuencode $ATTACH $(basename $ATTACH)
 echo "--$MAILPART--"
) > email_`date '+%Y%m%d_%H%M%S'`.out
| /usr/sbin/sendmail $MAILTO

嘗試在uuencode之后添加一個新行

並嘗試不帶-m
