[imp] Sent-mail folder issue

[Thomas O'Brien]

Hello,

Folks here use both IMP and Outlook to access their mail. An Outlook rule copies
sent mail to the IMAP sent-mail folder. Mail sent via Outlook shows up in the
sent-mail folder with the To field listed as " " and it appears that every
message like this generates a
Notice: Undefined index: fullfrom in \horde\imp\mailbox.php on line 777

If I open the message the From field shows:
"Thomas O'Brien"@slapshot.creativebusinessystems.com

I have no idea where to start troubleshooting this problem.

Any advise would be greatly appreciated.

Thomas
