That's really too bad.

True enough. Fortunately, I've got quite a lot of experience setting up
Internet e-mail systems. But that's why I think that, if you somehow could
change that darn From: line, there's a good commerical opportunity here.

Will it? Everything I've ever sent that was over-size was just truncated.
But I'd be keeping a copy in my regular mailbox, so that would be another
advantage of my system. (I wouldn't lose the extra data.)

Unless they accepted the message (I think they'd just do an SMTP reject,
wouldn't they?) AND were misconfigured to bounce to the From: line instead
of the envelope sender, it'd just come back to my system. Of course I'd
have the envelope sender set up to be delivered to a program that could
deal with this.

Yeah, but then I don't get instant notification of e-mail, which to my
mind is one of the best features. I also lose the ability to compose
a reply in an area with no service and send it when I get back into a
service area.
I can work around both of these problems with the kludge of sending
my outgoing e-mail back through my server (i.e., send it to my server,
which extracts a new From: line from the first line of the message and
forwards the mail), but that is extra work, which is annoying.

Again, if it were going through my system and I got a copy to my regular
account, I could do that. But here I have no headers and no envelope
sender, so I can't even see who it's really from. (Well, some spammers are
perhaps still dumb enough to use their real address in the From: line, but
something over half of mine these days use an obviously invalid addreess:
"0901234567@docomo.ne.jp", "foo@192.168.0.1", that sort of thing.)
The only good study I get out of it is practicing my kanji. :-)
I do intend to change my address soon, but that's not going to help for
all that long; the spammers can't stay this stupid forever. Anybody whose
mail address is four characters or less is doomed. Same for anyone with
one consisting of six or fewer Japanese syllables. Anybody with a common
name or word longer than that (English or Japanese), is going to follow
shortly thereafter. The ones with a single digit at the end will take a
little longer, and the ones with double digits rather longer than that,
but they'll all eventually go too.
I'm also hoping that docomo has been sensible enough to put a decent tech
or two on this; there are various things that they could do on their mail
servers to make life much tougher for spammers. I can think of a half
dozen off hand, and could probably find more if I saw their mail logs.
