The Wikmail doesn't appear to be available anymore and because of that I recommend checking Mozilla Thunderbird since it still available and updated with newest features and updates.
Typically, in Thunderbird you simply add the Yahoo account and it should connect automatically, but if it doesn't do that, consider using these settings:
- Incoming Mail (IMAP) Server
Server - imap.mail.yahoo.com
Port - 993
Requires SSL - Yes
- Outgoing Mail (SMTP) Server
Server - smtp.mail.yahoo.com
Port - 465 or 587
Requires SSL - Yes
Requires authentication - Yes
Your login info
Email address - Your full email address (name@domain.com)
Password - Your account's password
Requires authentication - Yes
