1.) Red Hat 8 is ANCIENT!!! Please, please, please upgrade to something more recent. It's bound to be riddled with unpatched security flaws.

2.) Squirrelmail has had plenty of vulnerabilities itself, like Cross-Site Scripting vulns. Make sure you're on the latest version (I'm not sure what that is).

3.) It's possible that there is some sort of index corruption with Squirrelmail that prevents all the messages from being displayed, or some other non-hacking-related reason. Your description is very vague, so it's impossible to tell you whether this is hacking or not. Describe exactly how the mail is accessed from "webmail" vs. "from outside". What are the differences? Different client? Different protocol?

The newest version of squirrelmail is 1.4.9a and 8.13.8 for sendmail, so basically you are just sitting and waiting to be exploited.

Looks like a bug with the webmail scipts?

More likely squirrelmail isn't configured properly. Which imap server do you use?

i dont know where i misconfigured the problem is only with that particular account only
