[SOLVED] strange mail problem

hello
my clients transferred their hosts from hostgator into my server.
After that their mail accounts cannot send/receive mail through outlook2003, 2007, thunderbird...etc
however they can login mail account through webmail and send/receive mail too.

I asked them to create new mail account. They did it and test that new mail account works without any problem. But their mail accounts(used in hostgator) keep throwing error that "cannot login pop server".

I have to fix this mess or my clients will go somewhere else.

Any help is very much appreciated.

Hello :)

Could you let us know which specific mail server settings are in use in the email clients? In particular, what is being used for mail server name?

Thank you.

Dear Michael
Thanks for reply. Here is what i did so far.

i tested
outlook express
outlook 2003
outlook 2007
thunderbird
windows mail
windows live

mail server settings are
pop : mail.myclients.net / 110
smtp: mail.myclients.net / 26
Server require authentication (checked)
use same setting as pop (checked)
user name : info+myclients.net

Also today i changed Dovecot to Courier

And i removed ssl cert. for all services then run
/scripts/updateuserdomains
/scripts/mailperm

i can login via cmd
telnet myclients.net 110
+ OK
user [email protected]
+OK
pass 123456
+OK Logged in
i can see all mails by typing list.

Also there is NO problem with newly created mail accounts. But mail accounts used before transferring keep failing.

Dear infoPro
I did as you said. still same.
BTW. I forgot the mention something in my previous posts.
Outlook can connect SMTP server(i am able to send test message to my hotmail account) but failed POP server.
In the mean while I can connect POP server via Command Prompt but i can notnot connect SMTP server.

Dear InfoPro
You are genius. I love you so much.
Finally problem solved. Without you it was impossible to solve this damn problem.

Here is last question:
Why cPanel shows info+myclients.net instead of [email protected] ??
Also why cpanel tells us that Server Require Authentication??

With my best regards
If you were here then i might kiss you.
