For the past week numerous bell mobility customers have been unable to send email from their shaw accounts with bell mobile data.
All receive the following message: 554 shw-obgw-4001a.ext.cloudfilter.net cmsmtp 174.90.223.*** is listed on cloudmark CSI-Global.
The last 3 digits on the ip address change but are all bell ip addresses.
I suspect that the shaw cloudfilter is blocking requests to shaws outgoing mail server shaw.mail.ca from bell ip addresses. Shaw insists the issue is 3rd party email apps and will only guarantee access via webmail.
Email works fine when connected to wifi but will not send on the bell mobility network. Issue exists using any of google mail, outlook and Samsung email apps. I think shaw has an issue and isn't willing to address it.
Any other bell mobility/ shaw internet users with shaw email address experiencing this issue?
@BRBob -- to block spammers/scamming from using Shaw's mail-servers, either:
1. your device is connected via your home WiFi through your Shaw cable-modem, which "authenticates" that you are allowed to send to Shaw's mail-server.
2. your mobile device is temporarily connected via any ShawOpen access-point, which again "authenticates" you.
3. will only guarantee access via webmail -- yes, if the user of the mobile device authenticates into Shaw WebMail, the message will be accepted & delivered.
4. you are Internet-connected via any other Internet Service Provider, such as Bell, and your E-mail program has "authentication" enabled. This sends your Shaw E-mail ID and E-mail password to Shaw's E-mail server to authenticate, which then allows you to send to Shaw's mail-server.
Note that the E-mail ID value in the "FROM:" field does not matter. Shaw's mail-server does not check that value.
For those Bell Mobility customers, they should configure their E-mail program's "outgoing SMTP-server" to the name of Bell's mail-server. Bell's mail-server will recognize that they are connected via "data" over Bell's network, and will accept & deliver the E-mail to any ID. Or, as above, the E-mail program can use "authentication", when connecting to Shaw's mail-server.
When I did a lookup for "126.96.36.199" and "188.8.131.52" and "184.108.40.206", all of them seem to be IP-addresses assigned to Bell. What is the complete IP-address? It's not your mobile device's IP-address, so there is no sense in trying to "hide" it.
