Thanks for all the responses from PDR60 & MasterC .I clear things out.

However,I have a question,is it correct IMAP port is 143,but not 141??? I remember IMAP port is 143...Anyway,the main thing is that you guys have clear things out.Port 25 is being blocked by ISP is reality.But I can still use my webmail because I relay all my mail to my ISP mail server.So,I can send and receive mail via webmail but not MUA.Because it is being blocked by my ISP.Is it correct?PDR60 & MasterC .

Thanks for all you guys every efforts to help me.

You are correct. Unless you want to use Dynamic smtp like I refered to, you will have to continue to use IMAP on 143. The reason for the "Relay Denied" was you were trying to relay mail off of your isp on 25. They would consider that Spam. Beside's lets hope they arenot running an open relay!!!

You will never get mail on port 25 unless the access list on your ISP's router is opened( I worked for an ISP for 2 years). It has nothing to do with your end. You can configure till the cows come home. If the ISP side of your connection is blocking port 25, Game over!!!! There are services that offer dynamic smtp. Folks like can overcome your problem by "proxying" your mail. Not a very elegant solution but it will work for low volume. However, If you are going to spend the money for dynamic smtp you Might as well just up your service to get your connection with all ports open

Thats your best bet. Just get the correct connection.
My bad, MasterC is a bit 'out of the loop' lately, my appologies for the port misguides Thanks for the clarification
