After an update, eClient fails to connect to the email account at Yahoo. Any suggestions?

Error message: [IMAP] An attempt to connect to account failed. This could caused by the temporary server unavailabillity…
Seems to happen right after the soft update.

Hi,

Yahoo IMAP authentication servers are known to not work at all or work only sometimes, we have introduced some workarounds to this issue, but we can’t solve this completely, because main part of this problem lies on Yahoo’s side.

So unfortunately until they will wake up and start doing something about their servers there will always be problems with IMAP under Yahoo.
