Hi everyone,

After I updated my CentOS and DA to the latest, I got a lot of messages about dovecot in logwatch file. This had not happened before I updated.
Could anyone tell me what happens to my server? Is there any solution to fix it?

Thanks,
@Sorry for my bad english :)

It appears your updated system is now doing more logging than your old system did. You can either make changes to what's being logged (you'll have to look up how to do it; I don't know offhand), or make changes to the program that's sending you the logs, so it doesn't send certain kind of logged information.

Is abc.com.vn on your server? If so, do those email addresses exist?

If not, the err lines simply point out that someone's trying to log in to an address that doesn't exist.

Thank jlasman,
So that is the update of the dovecot. abc.com.vn is not my real domain, i just edited when posting this question. Actually, all of those emails exist and users can log in successfully.
I think I could fix this problem, thank you!
