An email server receiving mail is normally assigned port 25/tcp is used for SMTP, the outgoing mail protocol, and is often blocked by ISPs to cut down on spam (whether intentional or due to infection). The block prevents users from sending outgoing mail via any third party mail-hosting services. We've watched what was once somewhat of a scattered practice quickly become an industry standard over the last few years.
The tactic is generally a good idea, and only causes trouble when the ISP fails to clearly inform users of the change, allowing them to employ fairly easy solutions. Some ISPs allow the port to be re-opened upon request, while others - like Comcast - only apply the filters when dealing with spamming accounts in the first place.
