Re: How to specify sendmail on command line?

Use this instead:

  mail -E"set sendmail=\"sendmail:$HOME/bin/sendmail\"" ...

Rationale:

1. URL must start with a scheme followed by column.  In your example,
it is missing, hence you get "URL missing required parts" error.
To be precise, Mailutils does allow for URLs starting with '/'
instead, but these imply the 'prog://' scheme, which is not what you
want anyway.

2. The tilde character is not expanded within URLs (whether it should
or not is another matter), so you have to use the $HOME variable to
expand to the absolute pathname of your homedir.

3. Single quotes would prevent expansion of $HOME.  Double-quotes must
be used instead.  Correspondinly, any occurrence on double-quote within
the string must be escaped.
