Solve : Emailing on another Wifi connection: can receive, can't send!? |
|
Answer» Whenever I am logged into another Wifi (eg on holidays etc) away from home, I get the same problem: I continue RECEIVING emails, but cannot SEND. My provider is Orange and PC is on Windows 7 (with Livemail). I have 2 email addresses but whether I USE my Orange or Gmail one, the problem remains. This message may get onto the forums or may not, let's see, but I may not be able to ANSWER you until I get home in a week's time, unless I can do something now to heal this problem. Simple Mail Transfer Protocol (SMTP) is an Internet standard for electronic mail (e-mail) transmission. First defined by RFC 821 in 1982, it was last updated in 2008 with the Extended SMTP additions by RFC 5321 - which is the protocol in widespread use today. SMTP by default uses TCP port 25. Because of security issues, many service companies put restrictions on SMTP. For example, AT&T is very strict, but Comcast is more tolerant. Therefore, when you travel to other areas and use another service, the SMTP will not work right unless you make changes to some settings. In some cases there is not way to get the settings right. The LOCAL company just rejects any SMTP that is not part of their own service. Use of a web based e-mail program can get around this problem. Example: If my provider is AT&T I can use Thunderbird are some other client at home. to send e-mail. But when I travel I must sigh into ATT.NET and send my email from the ATT.NET server instead of using Thunderbird. Con you see why? Thunderbird has to use SMTP. But if I log into the server I don't need SMTP. Does that help any? Thanks, Geek-9; I will contact my provider (Orange) when I return. But apparenttly I can SEND to this forum. Can you explain why? BobBecause posting to a Forum has nothing to do with how email protocols work... |
