I have some problems with the mail fetching, this is the second time that this happened in this month,

The service are working so good until today, I review the access directly by gmail.com(is a gmail account) and the account is working fine.

I followed these steps

- Stop the mail service 

- Put again the values required 

- Start the service

- Telnet test (OK)

- I checked the logs and I found this error:
