When I have traveled in Europe in the past, I have been able to receive emails in my Cox email account on a Windows laptop and an iPhone, but neither of them can send replies or new email. They sit in the outbox and never send. I thought I had this solved years ago when the telephone support guy said to use "smtp.west.cox.net on channel 465 with SSL" but that has not worked lately. I see old postings about some services having cox SMTP servers blacklisted, or something like that. Does anyone see an obvious problem and know a solution?
The worst think about this is that from my experience, the Cox SMTP server DOES NOT SEND ANY REJECTION MESSAGE, it simply accepts the mail as sent from your device, and then discards it, never sending it to your intended recipient. If this was a response to an important message, you look like an idiot because you will never have been responded. If you were sending an important message, you will never get a response (because it was never sent).
I had to switch my SMTP to gmail since I travel often and this was a disaster. (It has a minor drawback in that I couldn't figure out how to suppress recipients seeing my gmail address and sometimes thinking that is my primary address.)
My experience was even worse. I got error messages saying my password was bad. So I wasted over an hour trying to figure out the problem, eventually changing the password for my Cox email. Still no success, but by this time my account was blocked on Cox web sites because of too many attempts with invalid passwords. I then somehow managed to open a chat with Cox support, and after over an hour with a Level-1 tech who knew nothing about overseas travel restrictions, etc., a Level-2 told me about Cox's policy of blocking overseas access. The tech said he'd authorize my wife's account and mine, but that was two weeks ago, and it still doesn't work.
But now, thanks to the misleading error message, I have to go and change the password on all my devices: 3 desktop computers, 1 laptop, 1 NAS server, 1 tablet, 1 phone. What a colossal waste of time. And all because of a totally bogus error message.
Also, I just got back (to Nepal) from about 2 weeks in Tibet, where the government blocks most VPN's, everything Google, CAPTCHA's, etc. For customers overseas Cox blocks some of the same elements, making it harder to troubleshoot in places like China. (I'd expect similar problems in Iran, Russia, and other places where governments are likely to do such things.) When a government does it, we call it censorship. When a corporation like Cox does it, we call it free enterprise.
