[horde] IMP: display senders email instead of displayname

[A. Schulze]

Hello,

in times where messages have RFC5322.MailFrom lines like
   From: "DHL.COM" <faked_sender at non_dmarc_domain>"
it would be helpful if IMP display simply the mailaddress instead of  
the displayname.

more general: presenting the displayname to the receiver may be limited to
  - the receiver had already send a message to that sender
  - the receiver has the sender in a local addressbook
  - the sender is whitelisted by other ways

Are there any ways to modify how IMP display a senders address?

Thanks,
Andreas
