If the "another e-mail account" would get their act together and accept authenticated email over the submission port (587), then there is no conflict.
The purpose of a port 25 block is not to restrict the customers from accessing another email service. The problem is that customers and servers historically have used the same port and spam-bots "look" like servers, not customers. There needs to be a simple way to separate MUA from MTA traffic. Hey, wait! There is. So, they are restricting spam-bots while not restricting customer use of their MUAs. Lighten up on the ISPs and come down heavy on any email provider that don't accept port 587.

According the FCC, supported by several members of Congress, this is blatantly illegal. The idea is that on general purchased use bandwidth there should be absolutely NO PORT BLOCKING that would prevent any customer from using the purchased transport to gain access to the services of another content provider. Apparently this is coming to a head because of the AT&T intent to deploy fiber and give priority speed and bandwidth to their services at the expense of accessing other services, in some cases actually re-directing, say, a Google search to Yahoo so they get more traffic on their AT&T owned Yahoo search engine. This does NOT APPLY to specialized bandwidth purchases, only to day-to-day home and business cable, dsl and other, soon-to-be-released services over high-speed transport that is sold to the "general public:. In other words, they are watching out for the consumer.

Port blocking has some very legitimate uses. Such a law would serious screw things up. Source?

Comcast swore it wasn't them but I tested everything from the desktop PCs to the router and found that mail made it to Comcast but never made it to us. One day, after a month or so, the problem went away. Moral of the story: Comcast can do a lot of weird stuff without even knowing that they are doing it. It is quite possible that they are blocking your client's messages with attachments and they don't even realize it.
