Question regarding the use of double quotes in an email header

[mun_johl@xxxxxxxxxxxxxxx]

Hi,

The company I work for as defined everyone's email addresses as:
   "First Last" <address@domain>

Mutt seems pretty smart and automatically adds/removes the double quotes
on the outgoing email based on one's name (e.g., if a period is used).
But my company uses the double quotes on all addresses.  Okay, that's
not a big deal.

The reason I bring this up is because when I receive emails, the double
quotes and the text they surround appear to be cleansed from my emails.
And because of that--and that fact that I am using the old indent patch
(patch-cvs.jmy.indent.1)--the patch is essentially rendered null and
void.

Any ideas why I am not receiving the header intact just as it was sent?

Note that my company uses MS Exchange and I checked with someone using
Outlook, and the double quoted strings were present on the From: line.
But I don't see them on my Solaris 8 system running Mutt 1.5.15 .

Thanks in advance.
