Re: Ugh...

The only people that have need of port 25 outbound are ones who are running their own SMTP servers. The vast majority of providers prohibit the running of servers by their residential service consumers. So, to these providers, if their actions negatively impact your ability to violate your ToS agreement, it's only going to be viewed as a win.

For those of you that cry about this impacting your ability to use an SMTP hosting company's services (or even your employer's SMTP hosts) for relaying, that's a matter of implementation. Your SMTP service provider should be providing SMTP client service via an alternate port, any way. If they can't figure out how to do this, they really shouldn't be operating SMTP servers in the first place.

Why should anyone provide SMTP at an alternate port, except to get around blocks such as this one? Port 25 is the standard.

Port 25 is the MTA to MTA standard. However, RFC 2476, § 3.1 specifies port 587 as a standardized port for ESMTP based message submission.
