Issue with sender's 'From' address where display name is not quoted

The reformatting is done in MilScanner? Truly? Not your MTA?
And, apart from the looks, what detrimental effects does it have?
Anyway, if they aren't RFC compliant, why should you fix it for them? Inform
them if you like, then just ... Forget them;-)

 We have received email from a reputable list serve that has the following
format of 'From' address in the unmodified email header:

   H??From: Patrick A. Guida, Duffy & Sweeney, LTD <ali-aba at>

The internally delivered email has the following 'From' header:

   From: Patrick.A.Guida at, Duffy.&.Sweeney at, LTD
   <ali-aba at>

It appears they are not RFC-Compliant on the 'From' address since they did
not have quotes around their display name.

I have tested re-sending the email with the quotes around the 'display name'
and the delivered email shows the correct display name:

   Patrick A. Guida, Duffy & Sweeney, LTD [ali-aba at]

Versus the same email without the quotes around the display name:

   Patrick.A.Guida at

Do I need to go back to the list serve to get them to correct the format of
their 'From' email header, or is there an option in MailScanner that should
assume text before the <ali-aba at> is a display name?
