I'm always using a target list before so I haven't encountered this problem before. But after the new update/when I enabled "search engine to use" (I'm not really sure of the cause), I often have this error on the left side of my project name (there's a red exclamation point beside my project name): "2014-01-12 00:56: E-Mail login error for Donnell-Cathey9015@mydomain.com".
I got 5 errors (in different e-mail address) in 5 hours. I use my web hosting as my e-mail address.
When I click "test" and "blacklist check", it says there that it is working fine.
How can I resolve this one? Your views on this please? Thanks in advance!
