Hi, occasionally when checking my ISP with mail in Yosemite 10.10.5, i get the "invalis SSD certificate" box..

My ISP mentions i should i check the box to "trust: the cert, which is obviously not the way to fix this..

I figure this is Apple issue because other mail clients don't have any problem, Apple or Windows clients connecting via IMAP on port 143.

The fact it only happens sometimes, and i can temporary fix the problem vy changing authentication to CHAP, and back again to Password tells me its Apple..

Any other things i could do apart from using another client to connect?
