Re: Error message: CXSNDR Plus, why would the problem ONLY be with Cox webmail? Gmail and apps work fine. Re: Error message: CXSNDR That's what I'm trying to avoid. May be wrong, but If I do that, think I'd need to re-enter all my wireless devices again on the router? Error message: CXSNDR Had a strange issue began last night. I sent an e-mail at 9:55 pm. Got a reply and when I tried to reply to that message, the reply did not go and I got an error message with this code (CXSNDR) at about 10:30 pm which translates to: CXSNDR There was a problem with the sender's domain. Your email failed authentication checks against your sending domain's SPF, DomainKeys, or DKIM policy. The above is direct from Cox Email Error page. I get this message on a laptop AND tablet when using Chrome to access the Cox web-mail portal for either replies or new messages. I DO NOT get this error code and messages transmit correctly thru an email app on the tablet and thru Thunderbird on another laptop. Last night I called Cox tech support and he had me bypass the router and direct connect the modem to an old desktop unit. Before bypassing the router, the desktop got the same error message on the web-mail portal. After bypassing the router and with the desktop connected directly to the modem, the web-mail portal then worked correctly. Since the direct connection worked and the wireless connection does not, Cox thinks the problem is mine and not theirs. They are washing their hands of it. I don't agree and think that Cox changed some setting last night between 9:55 and 10:30, so that their email servers no longer "likes" the settings of my router that they accepted just a few minutes before.I tried to convince the tech that I couldn't be the ONLY one affected by this issue and have him escalate it, but he was having none of it. I've found several discussions of this error code (CXSNDR) issue in the past, but not my exact problem and no real solutions. Before I go to the factory reset, re-installation of the modem (and reconnect all my wireless devices), does anyone have ideas? Thanks, Ralph SolvedMail received from laptop, but not an Android tablet? A friend with a Comcast address does not receive my e-mail if I send with my Android tablet. They do receive e-mail sent thru Cox webmail done on the laptop. I know the e-mail is leaving the tablet because others including my gmail address receive the same e-mail. Any thoughts? Or, is this strictly a Comcast issue? Re: E-mail window won't expand Dare I say that they've fixed the problem? For the last week or so, the e-mail system has been working as it did before this mess developed. Let's hope this doesn't jinx it. Re: E-mail window won't expand I just looked at it again and the advertisement is gone. ONLY the little collapse arrow is there! Still, the message block remains shrunken and will not expand when the collapse arrow is clicked. Worthless Tech Support from Cox! Re: E-mail window won't expand Becky, please read this entire thread. There are NO setting which are better. It doesn't matter what view. The white space is to the right of the window with the e-mail and causes the message to not fill the screen. I need to scroll back and forth horizontally in order to read the entire message. The issue is apparently ONLY on a PC. I did not have an advertisement on my Android tablet with Chrome. Why would Cox create two different experiences? Just take the ads away, fix the issue and quit fooling with the system. First is was an inability to paste into webmail, now this. And you wonder why people are leaving Cox?? Re: E-mail window won't expand Been there, done that. Just did it again for Chrome. I almost never use IE unless something causes it to open, so cleaned it out entirely and the message page exhibits the same behavior. Tried it on my Android tablet with Chrome and there is no advertisement at all. Why doesn't Cox simply remove the ads from the e-mail display and be done with it. No one is going to click on them anyway. Re: E-mail window won't expand Webmail in Chrome with Win 10. The ad has ALWAYS been placed there by Cox. I had to collapse it to the right in order to expand the e-mail and be able to read it. As someone else said, simply remove the ad and have all messages open in full screen. I tried to attach a screen shot, but can't see any way to do so.
