The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

What does dovecot do?
Tags: Redhat Apache, https://www.usiff.com/
I just got this email from my server.

Certificate for dovecot on my.server.us was expired and a self signed one was created to replace it.  You should install a new certifcate  as soon as possible to replace the self signed one that was installed to replaced the expired one.

Why and what is this Certificate for dovecot?    My current SSL for my domain name usiff.com is current or at least I think it is?

Dovecot is mail server for IMAP and POP3 protocols.
Both those protocols can be use in SSL/TLS mode (like https is SSL/TLS version of http).
As usually SSL/TLS requires valid certificate. You can buy one, or generate self-signed one(email clients should issue warning just like web browsers).

So, does that mean that the protocols for my mail server are secured by the Dovecot?

So how offer should my server automatically create one?  That's the part that is really confusing me.   I just got the email today that told me that the server create one, which I never knew I had.

I mean Dovecot is capable of protecting IMAP/POP3 protocols with SSL/TLS.

I think, that someone noticed, that You are using selfsigned cert, and tries to sell real one to You...

Hello ravenpl,

One more question... Is Dovecot part of Redhat or part of the Cpanel software?

It's surely part of RH (at least version 5)
 
05.11.2008 at 09:11AM PDT, ID: 21542779
Yes it's RH5, does POP3S & IMAPS.  RH has a certificate server installed by default (look in /etc/pki) - it's actually OpenSSL.
Clever isn't it?

What You mean, RH ships You with default sels-signed cert, but You are advised to change it. What's so clever about that?
IMHO, it should not ship the default cert to force user to generate one(or buy).
