San Diego. Used to have earthlink via TWC- it was SLOW, but it always worked. Fast forward to Signature Service. Speed is now fine BUT email (Apple Mail) s intermittent. Anyone FOR SURE know the right settings? IMAP. On laptop: system= Mavericks. Another computer-Yosemite. The set up is not the same exactly.
TWC says it's apple. I doubt it. It's probably some ridiculous box checked or not checked. Authentication? No SSL. Anyone know for sure. port 587.
Solved! Go to Solution.
This is an older posting but I just set up my IMAP TWC mail on MacBook Pro running older Mavericks OS. The instructions as provided by TWC do NOT work. They say to set Incoming IMAP Server port to 143. DOES NOT WORK!. I returned that to the Mac Mail default port setting of 993 and my TW mail account now seems to send and recieve just fine. In Mail ver. 7.3 I have yet to find any way to view/confirm the SMPT outgoing server port of 587... But it's working.
