Error detected while processing modelines

[Cesar Romani]

I'm using the latest release of vim 7.3 on Win XP.
When I load the following text test.txt:

--------------------
From: unknownmail.com
Subject: Re: vim: how to use set indentexpr
Date: Sat, 11 Aug 2007 12:50:31 -0500

...
--------------------

I get the following error:
--------------------
Error detected while processing modelines:
line 2:
E518: Unknown option: how
--------------------

No matter where I put the second line on the text I get always the same
error with different 'line'.

Many thanks in advance.

Vim thinks it's a modeline because it's in the top 5 lines and it's
' vim: ..'. It's probably best to just ignore this since it will only
happen very rarely, or you can do ':set nomodeline' when editing emails.
(for example by detecting that file extension is .eml or something). -ak

Modelines present a potential (and in the past, actual) security
vulnerability. The standard plugin vim73/ftplugin/mail.vim
disables modelines because when reading mail anything could be
present in the text. So my advice to the OP would be to ensure
modelines are disabled before reading mail.
