目标：使用HTML正文和二进制附件发送邮件(使用sendmail).

遵循以下链接中指定的准则

它的工作范围是HTML主体或带有uuencode的二进制附件,但不是两者兼而有之.

下面给出了sendmail的shell脚本片段.有了这个,HTML正在变得很好,但是附件被错误地编码/解码并且无法查看相同的内容.

请指教.

#!/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.
通过论坛和网页搜索,发现主要参考PHP,Python等.

将电子邮件中的内容传输编码类型从base64更改为uuencode解决了该问题.
感谢到目前为止的输入.

下面给出了修订后的脚本.

#!/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
