Exim does not generate tabs! I hate tabs; they cause endless problems.
This seems to be another one.

Yes. Stupid code. For a start, RFC822 does not require space after
"From:". Secondly, wherever it allows a space, it also allows a tab.

Exim will only generate a From: line if you do not supply one yourself
in the message, and if it does, there should be exactly one space after
"From:". How did you create these messages? Is it some MUA that is
generating these tabs?

Looks like the best solution. Maybe this should be pointed out on some
Linux group? I would change "6" to "5".

I don't think so. Even if Exim did generate tabs, the resulting lines
would be perfectly legal.
