couldn't send email

Last week when I was out of town, my netbook repeatedly refused to send
any emails, although I could receive them.

The typical error message was:

An unknown error has occurred.

Subject 'Re: Link for Remote Control of Computer'
Server Error: 421
Server Response: 421
Server: 'smtp.ultrasw.com'
Windows Live Mail Error ID: 0x800CCC67
Protocol: SMTP
Port: 25
Secure(SSL): No

Since I have returned home, "Send" appears to work again. Does anyone
have any idea what was going on?

Port 25 requires a direct connection. You will need to contact them to
find out the optional SMTP port you can use. It may be port 587 with SSL
enabled, but that's just a guess.

Thank you, Bruce. Does your comment still apply if I connect via Wi-Fi to my
DSL modem at home?

Not necessarily because you are connecting wirelessly to the modem, but
the modem is directly connected to your ISP whereas on the road, it isn't
the same.

Thanks again, Bruce. Should I try changing the port to 119,143, or 587
if the problem happens again? Does the fact that the road Wi-Fi is
unsecured have anything to do with it? I'm password protected, but not
SSL. I've been on the road before when everything worked with unsecured
Wi-Fi.

119 is for news. I don't recall what 143 is used for. It is most likely
going to be port 587 or 465. I know Cox uses SMTP port 465 on the road. At
home, 465 and 25 both work, but SSL must be checked with 465 and not
checked with 25. SSL (Secure Sockets Layer) has nothing to do with your
password protection, or using Wi-Fi, it is that some ports require it be
checked.

You can wait until you're on the road, or ask your ISP ahead of time.

Thanks, yet again, Bruce. I will keep you email listing ports, and I will
check with my ISP before we go to San Diego the first week in August.

when accessing mail servers from outside of your normal transit network,
many such "foreign" networks block direct access to port 25 because of
issues with spammers using outbound port 25 to upload spam to MX servers.

Many email service providers now use standard message submission ports, as
described by Bruce Hagen, to allow their user to connect when they are not
directly on the service transit network.

You may either ask your provider if they offer message submission on these
standard ports, or just try for yourself. Trying 'smtp.ultrasw.com' using
the Telnet command, and relevant ports. Port 465 fails, but:

| C:\Users\Norman>telnet smtp.ultrasw.com 587
| Connecting To smtp.ultrasw.com...
|
| 220 post02.dakotapro.biz ESMTP DakotaPro Welcome
| quit
| 221 2.0.0 Bye
|
|
| Connection to host lost.

I was able to make a connection using port 587.

Thanks, Norman. I will also save your email, and as I told Bruce, I will
call my ISP before our next trip.
