- Port 25

(Is it FCC or FTC? The article and the headline do not agree.)
There are two (misguided) critiques of ISPs blocking egress SMTP traffic:
1) It will prevent roaming users from sending mail. This is incorrect. Roaming users ought to be connecting to their SMTP server using port 587 (or 465 for SMTP+SSL). Port 25 is not for initial mail submission-- it is for mail transport. Mail server admins that can't figure out how to configure the user of SMTP+AUTH+TLS on port 587 or SMTP+AUTH+SSL on port 465 should think about another career. "But we can't expect all of Comcast's users to reconfigure their e-mail clients!!" You don't have to-- only roaming users. The vast majority can continue to use the antiquated port 25 for IMS, Comcast can "trust" them since they will be coming from within their network.
2) It will prevent amateur mail admins from running a mail server on their consumer DSL or cablemodem line. Correct! Running a mail server is a serious responsibility. Admins need to be held accountable for the operation of their server(s). Not only is running a mail server on a DHCP consumer line usually against the AUP of the ISP, the resulting outgoing mail looks like spam (it certainly won't pass SPF muster). Sorry, but if you want to run a mail server, either get a business account (no blocking port 25), or convince your ISP to give you a static IP address and unblock port 25. Now they can easily find you if there is abuse. - Posted by: RestonTechAlec Posted on: 05/23/05 You are currently: a Guest | Members login | Terms of Use
