<It actually has nothing at all to do with wireless.>
Hmmmm, I must have gotten confused, because the initial "problem" I
brought to the list last summer when I got my iBook (with built in
Airport) was that I could not SEND email with CE via Airport using a WiFi
hotspot. Pick up, yes, but send, no. And that was when you mentioned the
Port 587 version of CE and said I could download it at your site. ;-) So
I apparently I erroneously tangle up CE Port 587 with wireless in my
deteriorating mind. Anyhoo....
<Email is transfered between mail servers via the SMTP protocol (a
particular set of commands and data used for transferring email).
Email clients send email to servers using the same SMTP protocol.
SMTP works over port 25. All networking software uses "ports". A port
is basically a specific location in the network stream.>
Ah-HA. You know when I originally read this email earlier today, I just
had the urge to grab my CE Port 587 equipped iBook and run to the closest
WiFi hotspot to try to send myself a test email (I have two email
addresses) -- more like looking for the error message than actually
expecting to be able to send an email. No, the email didn't send (I
wasn't surprised), but Logs showed up with a "network stream error"
message. So,
<So the Port 587 version of Emailer simply changes emailer from
sending out email over port 25, to sending it out over port 587. If
you are a person that travels or otherwise regularly runs into ISPs
that block port 25 access, then the Port 587 version may be of help.
*Use of the port 587 version of course assumes that the mail server
you are connecting to supports receiving email over port 587. Not all
mail servers do,* although it is something that is starting to be
adopted more and more.>
*starred section my emphasis* and
<*the ISP you are connected to is also blocking port 587.
Unusual, but possible, and with public hotspots, I can see they may
still block it to be extra careful with blocking the sending of spam.
The other possibility is the mail server you are connecting to at
those times is refusing the connection. It could be due to the
authentication method you are using*, or maybe you are changing mail
servers and the alternate one simply doesn't support port 587 at all.
So, is it therefore correct to assume that when I can't send email using
CE Port 587 and a WiFi connection, it means that the provider of the WiFi
service doesn't support email over port 587, and since 'ports' are
"specific locations in the network stream" -- this is why my email won't
go out and I end up with the "network stream error"?
Hmmmmm....authentication methods....Well with CE being so, shall we say,
venerable...maybe I ought to see if something newer might work with the
WiFi connections, i.e., :::::shudder:::::Apple Mail? When I feel like
going out again, I'll try sending myself a test email using Mail, just
for the heck of it.....
<As for "wireless dialup", if I had to guess, he simply has a wireless
access point connected to dialup internet service instead of
broadband. The original model Airport Base Station supported doing
this, it had a modem built in and could dial on network demand. I'm
sure there were other vendors that made similar hardware (I know
there were pleanty of dial on demand routers on the market, so I
don't see why some of them couldn't have had wireless built in, or
you could simply daisy chain the wireless access port to a dial on
demand router and get the same effect).>
I honestly don't know the details on how he set that up ("wireless
dialup" is HIS name for it, LOL). All I can tell you is that he did it
entirely with his Linux stuff (which I know nothing about), Ethernet
(which I don't know much more than nothing about), and he uses his own
regular dialup internet account (for which he has a 56K modem). For me to
use it when I'm at his place, I turn Airport on in my iBook, and I get a
network called "default." If I select this "default" network, I can
receive email with CE 587, send email with CE 587, surf the web and chat
to my heart's content.
