Re: Comcast cut off outgoing SMTP server

said by englund:

I understand that the client shouldn't be using Comcast for this type of mailing (unfortunately the client did not). The bummer is that Comcast doesn't appear willing to allow access to the outgoing sever on this account and now several of their POP accounts (that don't have a mail server) no longer can sent mail.
I would suspect that the client has had a port 25 block imposed on them. Comcast will impose a port 25 block on outbound connections when they perceive that the subscriber is being abusive. The last word that I got was that the block will remain indefinitely.

Have the subscriber reconfigure their client to use port 465 with SSL. It that works, fine. If not, well; they were using the service improperly. There are many options. I got tired of the spam to my ISP account and set up my own domain.

Well no one wants to send out business emails with AOL, Hotmail, Gmail, etc accounts. (These are legitimate emails about the organization - not unsolicited junk.) They have their own domain (as well as several client domains they manage) and so use their domain email with a Comcast business account (not residential service). So you'd think if you call customer support they wouldn't give you some baloney line about a company wide policy about banning outbound connections but would instead inform the client what a block had been placed and why.

GMail and Yahoo! Mail Plus allow you to send email from your domain. Here are examples, including screen shots detailing a reply composition:

Just to prove a point about GMail SMTP service.
Despite the "Return-Path:", and "Sender:" header lines, the recipient's client will only display the "From:" header line, and will open a composition window to the "From:" email address. This is not a GMail email address!

Just to prove a point about Yahoo! Mail Plus servers.
There are few clues that this went through Yahoo! servers. No 'yahoo.com' email address. The "Organization" string can be changed in the client (I just don't feel like re-testing after changing it; there is a setting for in in Pegasus Mail). Note that Pegasus Mail even let me specify the "HELO" string (lycos.com), despite that this message did not even go through Lycos servers. BTW, Lycos Mail Plus works similar to Yahoo! Mail Plus; as an option for using SMTP servers other than Comcast. I do have a Yahoo! Mail Plus account, courtesy of AT&T HSI (sort of like Comcast and Giganews). I don't have a Lycos Mail Plus account.

The screen shots show what the recipient sees in the message list, and the reply composition window.

Bottom line, though, to get somewhat back on topic: Nobody should be using a residential ISP service for business purposes. You need to mail large quantities of messages on a regular basis? Your own domain, and mail hosting for that domain can be had for under $70 per year.

I skimmed over most of the messages and did not see this so I apoogoze in advance if someone mentioned it. In a effort to reduce spam, Comcats (as does many other ISPs) only allows their SMTP servers to be used if you are connected through a Comcast IP address. If not, you will be blocked. So therefore, if the OP had a non-Comcast IP the SMTP would be blocked.

That is not true. Aside from examining the headers of the message I posted earlier, fourth one (it shows access to 'smtp.comcast.net' from a 'pacbell.net' (AT&T Yahoo! HSI) IP address), check your Comcast site FAQ for configuring an email client to access 'smtp.comcast.com' from another network. You must configure your client to use SMTP AUTH when connecting from another network.

BTW, my ISP, which is AT&T Yahoo! HSI, like Comcast, does allow authenticated connection to their mail servers from other networks.

In fact, here is the instruction for using Outlook Express while travelling (and not being connected via Comcast). There are similar instructions for Outlook and other email clients.
