Email server was working quiet fine, but now i can not receive email when i check error log it shows this error message

localhost fetchmail [4917]: server certificate verification error : certificate has expired.

good people can you help me on this problem.

The server you're fetching the mail from needs to renew it's ssl certificate ..

 

is it the ISP server or the local server, and how can i go about it

 

no no, listen up:

with fetchmail you can grab mail from another server and put it in your own mailbox .. now my question was ..

from which server is fetchmail grabbing that mail from..
