Hi,
I'm using Sendmail with mimedefang.
Recently a co-worker was having trouble with a company facebook
account and got Facebook to send her a 'reset-password' email.
When she received it, it came only with the following message:
This message contains a rich-text HTML portion. Consult
your mail client's documentation for information on how to
view it.
After I disabled mimedefang, the e-mail went through properly.
My question is, how come I couldn't find This message ...
in mimedefang's sources?
I know that mimedefang alters e-mails. I'm just curious
as to where this message came from if I can't find it
in the mimedefang sources. I guess, ergo, it isn't mimedefang;
but, re-enabling it gives me that message.
Any clarifications appreciated.
Have a look at http://tools.ietf.org/html/rfc2046 and search
for the word preamble. The lower part of page 20 shows a simple
example of a message with a multipart message body that contains
a preamble, two text parts and an epilogue.
In short: the preamble of a multipart mime entity is an optional
text preceding the part(s) of the multipart entity.
The preamble is normally not shown by mime-aware user agents.
It looks like you received a multipart message with a preamble
and only a single HTML text part and that you instructed mimedefang
to delete the HTML part. That leaves the original preamble as
the only contents of the resulting message body.
Regards,
Kees Theunissen.
