Have a client with 4 pop3 email accounts on their company domain hosted by a company called Intimation with BT-supplied broadband. Yesterday both their incoming and outgoing email stopped working with no changes made to their internal systems. Outlook Test Account Settings returns “Outlook cannot connect to your incoming email pop server.. error 0x800CCC0E”. Telnet &lt;mail server’s ip address&gt; 80 fails. So as if something firewall-related blocking port 80. But now for the weirdest bits: Setting up a test email account not attached to the company domain WORKS… and setting up one of their email accounts on a pc at another site WORKS. Taking a laptop with their email setup on it FAILS at their site but WORKS at external sites. Router has been replaced with a new one out-of-the-box (so no firewall rules) to no avail. As if their mail server is blocking their IP address for some reason (though this is denied by tech support). How odd is all this?!

Company email blocked at premises but not elsewhere!

An email client, email reader or more formally mail user agent (MUA) is a computer program in the category of groupware environments used to access and manage a user's email. A web application that provides message management, composition, and reception functions may internally act as an email client; as a whole, it is commonly referred to as webmail. Likewise, email client may be referred to a piece of computer hardware or software whose primary or most visible role is to work as an email client. Email clients can also have other systems, like calendars, notes and contact managers.

Microsoft Outlook is a personal information manager from Microsoft, available as a part of the Microsoft Office suite. Although often used mainly as an email application, it also includes a calendar, task manager, contact manager, note-taker, journal, and web browser.
