Dirty Harry:1. Ability to turn off the reply option popup everytime a reply is made.
You used to be able to turn it off. So everyone turned it off. Then they forgot that it was even there. Then they complained that Pegasus Mail couldn't do a whole bunch of useful stuff. So we had to continually tell them to turn it back.
In other words, the ability to turn it off caused a LOT of problems.
Dirty Harry:2. Ability to import addressbooks and messages. (.eml .msg, comma delimited)
There are good, free, utilities to import address books. It would be too much work for David to try and write import/export filters for various address book formats. Many mail programs do not publish their addressbook formats, so it would be a lot of reverse engineering every time they changes. For addressbooks, try Dawn: http://mysite.verizon.net/zakharin/software/Dawn/
For messages, you can rename .eml files to .cnm and place them in the new mail directory. Pegasus Mail will see them as new mail messages.
I don't know about .msg files.
Dirty Harry:3. Include "AND, OR" logical operators in mail filtering rules. (from contains katieb OR kathyb OR Kateb move to folder Kathy)
Already available. Set the action to LOGICAL AND or LOGICAL OR. Check the Pegasus Mail help files for the topic "Advanced filtering - flow control and logical operations".
Dirty Harry:Also ability to match the addressbook.
I don't know what you mean by this.
