Jeff,
In looking at RFC 821, it defines a maximun length of a 'text line' as "The
maximun total length of a text line including the <CRLF> is 1000
characters...".
Since all command and reply lines MUST have <CRLF> and the text line says
that too, strict interpretation means that <CRLF> and <LF> are not
equivalent (they would not be the equivalent on a 'terminal', either)!
A line with only a <LF> would look something like this:
'abcdefg
hijkl...'
Of course this is a bit hard to show in an email client, but I hope you get
the idea!!
Taken one step farther and <LFCR> is not the same as <CRLF>! Servers may
handle this in different manners (some might add a CR to a single LF, others
may not, RFC does not address this, at least the one I consulted). So it
does mean that your implementation may have some problems if it does not
have <CRLF> as the terminating characters of a 'line' or 'command'. This
problem could also be the cause of the premature termination of your email
message. If the data stream contains a <CRLF>.<CRLF>, IMail will interprete
that as the end of the DATA command. A '.<CRLF>' sequence is not enough to
cause IMail to think this is the end of the DATA command. I tried several
sequences with a single <CRLF> and a '.' (differing orders) and all worked
as expected. I did not try any sequences with only a '<LF>' (could not
figure out how to do that from the keyboard), but the RFC implies that a
line with only a <LF> as the terminating character, should not be be seen,
but it would not be prohibited <LF> within a line that is terminated
correctly.
So the answer to your question is 'NO, <LF> or <LFCR> is NOT the same as
<CRLF>'.

Subject: [IMail Forum] FW: email gets trashed
> Ever since I switched to my own server running Imail 6.0, when I get email
from one of my Cold Fusion pages, it gets trashed. My

> There is still a bigger problem, when I email to both my Imail account and
my Mindspring account, I get very different results:

> FROM MINDSPRING:
> line = 0 The following information was submitted from the Contact Us
page.line = 1line = 2line = 3line = 4 Hello world

of '=' characters, it really returns strange results.

something).

> Anyone know anything about this. Shouldn't LF be just as good as CRLF for
internet protocols?
