Eudora 1.4.3

Error

There has been an error transferring your mail. I said:
Pass
and then the POP server said:
ERR Password supplied for "username" is incorrect.

Solution

Passwords need to be typed in exactly. They must not be changed. Check to see if the caps lock key is pressed to make sure that the letters are in the right case.
The other posibility is that your username was typed in incorrectly. Check the username if it is wrong you can change it by clicking SPECIAL then CONFIGURATION and retyping the POP Account name: it should be entered as your email address (ie. jsmith@computan.on.ca)

Error

Eudora Network Timeout
Eudora is tired of waiting for the system to respond. Press OK if you wish to continue waiting. Cancel will terminate this connection.

Solution

Sending attachments to email is not the most reliable way to transfer files. If the file can be downloaded from the Internet it is better to send the recipient the address of the site where the file can be downloaded. The error is caused when the modems stop communicating. This is caused by poor line conditions which lower the transfer rates between modems.
