Leo, I am a Charter Cable customer and as a result, I have a charter.net
email address. I travel every week, and when I am away from home, Charter’s
email will not let me SEND email when I use Outlook. I can receive email all
day long using Outlook when I’m off the Charter ISP, I just can’t send any
email. Now, using my iPad, it works just fine! But using my laptop? It’s a
no-go! I have questioned Charter about this several times and each time, I get a
“canned” response from them and they want me to jump through hoops. They know doggone good and well that it isn’t going to work, regardless of what I do. I
have a sneaky suspicion that it has something to do with their nasty, ugly,
user-unfriendly web-based email system! I downloaded Thunderbird after reading
your newsletter, but that didn’t work either. Have you got any idea of a setting
or something of that nature that I can adjust/change that might make my Outlook
work with my Charter email address when I am away from my home base?
First, don’t blame Charter.
Well, blame them for not being able to help you perhaps, but don’t blame
them for the situation. It actually has a perfectly logical explanation.
Instead, blame spammers.
I’ll look at the common solution and then explain a little about why this
might be.

These settings are typically buried in the account configuration in your email program. In Outlook 2010, for example, click File, Account Settings…, click the email account in question, and click Change…. In the resulting dialog, click More Settings… and then the Outgoing Server tab. Other email programs will have this setting in different configuration-related places.
As I said, which of those two options that you need will depend on your ISP, but they are both designed specifically to allow ISP customers to send email using their ISP’s servers from anywhere.
One other possible issue
The default “port” used to send email is port number 25.
Unfortunately, port 25 is often blocked, or worse, hijacked by hotels and other businesses that provide internet connectivity – once again in order to prevent spam.
Why can’t I send mail from my hotel room? talks about this in more detail, but the bottom line is that if your ISP allows you to use a port other than port 25 to send email, use it. You can use it regardless of where you are, whether you’re at home or on the road.
While you’re at it, look for the options to use SSL or TLS to encrypt your outgoing email and use those if you can. When encryption is not used, anyone with access to the network may be able to sniff network traffic and read the email that you’re sending. (You might also consider the equivalent SSL setting for your POP3 settings, used to receive email.)
It’s all about trust … and spam
First, realize that anyone can connect up to your ISP to try to send email.
Anyone.
And, of course, that includes spammers.
When someone tries to send mail to (or through) your ISP, it has three things that it can check:
-
The send attempt is via an ISP-provided connection. For example, your ISP provides the connection to your home, so they know that it’s you or someone at your home sending email.
-
The send attempt is trying to send to a customer of the ISP. In that case, the ISP accepts the email regardless of where it comes from so that it can be delivered to that customer.
-
The send attempt is made by an authenticated ISP customer. As we saw above, authentication allows the ISP to know who’s sending.
The scenario that’s left out is this one:
-
The send attempt is not via a connection provided by the ISP, not by an authenticated ISP customer, and not destined for a customer of the ISP.
In other words, the email looks like it’s “just passing through”, having nothing at all to do with any ISP’s customer.
Left unchecked, this is one way that spam propagates. There’s no one in that path that the ISP can trust – sender or recipient.
By configuring your email program to authenticate first in some fashion, as described above, the ISP knows that it’s you and thus, they can trust that you’re not a spammer (or they can yank your account if you are).
One last possible glitch
Most email service providers like your ISP support this ability to authenticate in some fashion before sending.
Most.
It’s sometimes the case that they might not.
In a case like this, I’d be tempted to find another email provider for everything. More practically, you can send using a different service than the one that you receive on. Gmail is often good for this if you have a Google account. It’s easy in concept (just configure the SMTP settings for the other service), but sometimes there may be ramifications; it’s easy to get the “From:” address wrong on the email that you send and your Sent mail may not be saved as it was when sending through your ISP directly.
Whenever possible, it’s still probably a good idea to send using the services provided with your email account.
You mention gmail as a possible solution. However, I think you missed a possible “simple” way, using gmail, to solve this problem.
I have Verizon at home. While at my sister-in-law’s house for a while, I was unable to send e-mail, even with “sender authentication” enabled, simply because Verizon’s outgoing e-mail servers wouldn’t accept a connection from a Cablevision (my SIL’s ISP) client.
I found that I could tell my e-mail program (Thunderbird in my case) to use the gmail servers I had already set up for my gmail account as the default server while not at home. Since Thunderbird was already taking care of all the housekeeping with the “correct” e-mail address I was sending from, that wasn’t an issue. The only thing that changed was, behind the scenes, Thunderbird would contact gmail’s outgoing e-mail servers rather than Verizon’s. The “from” remains the same; it’s still copied to my “outbox” folder”; nothing else is different from my point of view, aside from the fact that it “works” from non-Verizon connections.
I would suggest getting a free gmail account (even if you have no plans on actually using it for anything else), and setting it up as a personality/account/whatever your e-mail program calls it. Make sure you can send e-mail with your gmail account through the gmail servers. Then, when you are on the road, simply tell your e-mail program to use the gmail settings you have already set up, and use then as the “default outgoing SMTP server”. (In Thunderbird, it’s pretty simple. Just go to “Tools / Account settings”, scroll down to “Outgoing Server (SMTP)”, click on your gmail server settings, and click “Set default”.)
In fact, you could keep gmail as the default server even when at home. (Though I always put things back to Verizon when I come home.)

I provide computer services in an area served by Charter. I can tell you that they have a way of allowing you to send through a different server when you are out of their network.
However, you can’t use this same server when you are ON their network. For the user with a portable computer, this can be very frustrating. I normally recommend that my clients use an e-mail service (e.g. Gmail) other than Charter’s for this very reason. I also recommend it so they aren’t tied to the ISP for e-mail since people do change ISPs from time to time for various reasons.
I used to use a service called mail to web or web to mail -it’s been awhile- and it allowed you to tie all your email programs into it, both from your ISP and your web mail accounts. It was handy but the one issue with it was when I downloaded mail with it, the emails stayed in the inbox of the program. If I needed a record of something on my home PC in its Outlook I had to remember to forward copies back to myself. It wasn’t that big a deal- just tedious. I use all my ISP allowed email accounts, some 5 of them, and each has specific uses. One I wouldn’t use with the web to mail so I wouldn’t keep receiving the same mails again. Of course, you can also check the ‘leave a copy on my ISP server’ but that can create other issues if you forget to clear it or you get a lot of email and fill everything up.
I’m sure there are other modern programs that are available that have that all worked out. I know my ISP currently has a service where you can check your mail, both send and receive it, through their web site.
I regularly commute between Hong Kong and Manila and when doing so had to go through the process of reconfiguring my outgoing addresses in each place. I now use the SMTP2GO service. I set this as the outgoing server for all my Outlook accounts and can send using outlook from anywhere. So far (2yrs) it has been trouble free and ‘set and forget’.
This isn’t something like the Verizon Port 587 convention, is it? If I use the default Port 25, I can’t send from anywhere off the Verizon network; they sent out the “Port 587” fix a couple of years ago. I would hope that Charter would tell you if they did something similar.
I have the opposite problem with Charter. I can send from my laptop when on the road (I use Outlook), but can’t get my mail to view on my iPad. I can get into my account, but it won’t load past the first screen. That happens at home with WiFi as well.
This is one of the frustrating aspects of being a Charter customer. Would be less of an issue if their webmail page wasn’t such an archaic, slow, ad-heavy pain-in-the-arse. Why do they subject their paying customers to this?
Currently I’m staying in Vietnam. Got some big headaches using the free wifi here, because I couldn’t send out my urgent emails to my German clients. Like my previous poster Duncan, I’m using Smtp2go ( reference : http://timreviews.com/cant-send-mails ). So far everything works smoothly..finally.
Thank you Leo, for your article,
