Welcome to the forums,
Actually there's Yahoo IMAP access, it's just restricted to allowed apps with special auth like
Yahoo GO, iPhone(?), or
Zimbra Desktop.
In the current publicly downloadable version it's hardcoded so you can't put @ymail.com or @rocketmail.com or @yahoo.tld - will add this ability in a future release. Bug 29308 - support other domain names for yahoo mail What confuses people is that for a multitude of reasons the connection info given via help portals is just POP. ie: pop.sbcglobal.yahoo.com -Traffic is supposed to be pointed at the designated servers & there's also business reasons for only providing pop (and only to paying customers) from server scaling (& maybe even a little desire for wanting people to use the web-client to see ads or something - idn). The issue people hit: -You can't add as 'Yahoo Plus account' because your email ends in @someotherdomain but still Ymail powered content. -Then the naming constraint to prevent POP against any yahoo server. You can't add the account as type 'other' because it ends in pop.whatever.yahoo.com, which forces you to use IMAP. And other commonly guessed tries: pop.sbcglobal.net > auth exception pop.mail.yahoo.com > forces imap because of yahoo.com imap.sbcglobal.net > auth exception imap.sbcglobal.yahoo.com > unknown host (because it doesn't exist) Re ZDesktop forcing the use of IMAP because of the yahoo.com end of the server address - we intentinally restrict this. We don't use POP for Ymail or Gmail because that implementation will 'lockup' the entire mailbox for the entire POP session which can last a long time during initial sync and a few other reasons.
So, try creating an other account against-
Incoming:
imap.mail.yahoo.com (without SSL
- you get unrecognized SSL message message if you try encrypted connection (bug?)
or plus.imap.mail.yahoo.com
Outgoing:
smtp.whateverdomain.yahoo.com (with or without SSL)
or
smtp.mail.yahoo.com (with or without SSL)
or plus.smtp.mail.yahoo.com (with or without SSL)
(Tested against ZDesktop build 0.85.1191, build 0.85.1138 and the current release on website build 0.84.1119 using my personal sbcglobal.net account.)
Note: Official support for this configuration is Bug 27498 - offline - support for Yahoo business accounts

UPDATE:
Bug 27498 - offline - support for Yahoo business accounts &
Bug 29308 - support other domain names for yahoo mail are fixed for the next public release. And there's even access for non-Plus users
