I am looking for a simple line of code to incorporate in the program below which send a zip file to the user as an attachment. Here is my program:
proc EmailSendMessage {args} {
# Verify and set the command line arguments.
set requiredArgs {-recipient -subject -body}
set smtpServer 10.10.125.10
set smtpPort 25
set originator [email protected]
set token [mime::initialize -canonical text/plain -string $body]
mime::setheader $token Subject $subject
smtp::sendmessage $token -recipients $recipient -servers $smtpServer \
-ports $smtpPort -originator $originator
mime::finalize $token
}E-mail attachments constitute a surprisingly large and even unwieldy subject. The first clarification is to distinguish emission of e-mail with attachments, from its reception and interpretation. The Wiki page on the MIME package focuses mostly on the latter.
2002-10-31: Roberto Mello provides the following example:
package require mime
package require smtp
set rcpts [open email-list.txt]
set files [lsort [glob *.JPG]]
set text {Ooops! Some of the pictures got mixed up in the last e-mail.}
append text \n {Let's try this again.} \
\n \n {Happy Halloween!} \
\n {Your friendly MASA Villages Staff}
set i 0
while {[gets $rcpts rcpt] != -1} {
set this_image [lindex $files $i]
# create an image and text
set imageT [mime::initialize -canonical \
"image/jpg; name=\"$this_image\"" -file $this_image]
set textT [mime::initialize -canonical text/plain -string $text]
# create a multipart containing both, and a timestamp
set multiT [
mime::initialize -canonical multipart/mixed -parts [
list $imageT $textT]]
# send it to some friends
puts "Sending to $rcpt: $this_image"
smtp::sendmessage $multiT \
-header [list From {Juliane Mello <jmello@usu>}] \
-header [list To $rcpt] \
-header [list Subject Ooops!]
incr i
}The variety of ways to transmit e-mail attachments with Tcl is large. CL keeps a few models in [L1 ].
One of the reasons for active interest in the range of possibilities is typical for Tcl: one wants to compensate for various constraints. mime had severe flaws before tcllib 0.8 (and still has other errors--more on that, later) and is essentially unreliable with Tcl before 8.2.
CL frequently needs to set up quick e-mail operations on hosts equipped with old interpreters; 7.6, for example, in the case of a client met in January 2002. For older interpreters, it's best to enlist outside help, as with
set tmpfile /tmp/abc[pid]
set subject {This is the subject line.}
exec /usr/local/bin/mpack -s $subject -o $tmpfile $standard_name
set To {The distribution list}
set recipients {[email protected] [email protected] [email protected]}
set recipients [join $recipients ,]
exec $sendmail -t << \
"To: ($To)
Bcc: $recipients
[exec cat $tmpfile]"Mutt: Someone had contributed a mutt example that was not correct (mutt tossed back a "bad usage" message). CL's taken the liberty of simplifying the example from four lines to one, in the process of correcting it:
exec mutt -s $subject -a $attachment $to << $body
Other useful external Unix utilities include pine and uuencode [give examples].
CMM: Can anyone enlighten on the proper way to unencode incoming binary attachments for output to disk?
CMM: Note for the unwise (like me), properly used the mime package will automatically unencode base64 encoding by default. My issue was that I wasn't outputting in binary mode. To fix this: fconfigure $fileid -translation binary
FP: Another useful Unix utility for this job is UUDeview
uuenview -b -m [email protected] -s {The Subject} filename
