I was having trouble updating the password used for SMTP in Eudora 7. I couldn’t find a way to enter a new password, or get the client to forget the currently saved password. (Maybe be an issue with Gmail server sending a generic error message, rather than telling the client they have the wrong username/password?)

To manually reset the saved password in Eudora 7, close Eduora and find the Eduora.ini file located in:

C:\Documents and Settings\<user account>\Application Data\Qualcomm\Eudora\

Change the following lines from:

SavePassword=1
SavePasswordText=<randomtext>

To:

SavePassword=0
SavePasswordText=

Next time Eduora tries to send mail it will ask for a new password.

On a side note: Eduora apparently store passwords in plain text in an ini file… (Base64 doesn’t count).
