you may only have those two entries, I have about a dozen. I create address books for just about everything. I keep Mozilla related addresses in a Mozilla address book for instance.

I have heard over the ears that occasionally an address will still appear in the suggestions list after it has been deleted, until Thunderbird restarts. Something about the in memory cache not catching the change. Is this perhaps what is occurring to you?

Write a test message. Type the mystery address in the address field. Save to Drafts. I do not access to Thunderbird right now to test but in the Drafts folder or after you reopen the mail in the Composition window you can click the star to the right of the address and open an edit dialog. There is a delete button in that box.

This is from my memory so no guarantees. But it is close.

To: Airmail Thanks for suggestion. It took me a few times through the process, but eventually I found the yellow star when I selected my draft test message. A right click on the star gives me the option to "edit contact." When I go to edit contact, it says contact can't be changed because it is "in a mailing list. " A search of my mailing lists came up negative, but I did find unwanted and obsolete e-mail address as an "additional Email" in the "contact window" for the contact. Once I deleted the incorrect "additional e-mail" contact, it no longer was suggested when entering the name into the "To:" field.

Obviously the match function during address entry searches the "additional e-mail" field, but match function ignores entries in the "additional e-mail" field when being asked to search contacts.

Thanks for the suggestion and hope my explanation helps others if they have the same problem
