username -> real name lookups

[Grant Beattie]

I would like to turn off username -> realname lookups, as well as
remove my own real name from the From: line. ie, from Mutt, I want
the headers to look like:

From: grant
To: joe

Reason being that the mail configuration at another site translates
'grant' into Grant.Beattie, so having the real name as well as the
address is superfluous. The same goes for the recipient.

I'll obviously need to do something to the config to remove the
domain, too..

How can this stuff be done?

grant.
