ug.  I didn't even think of that.  Using a % instead of a @ was a 
popular anti-spam hack used by ISPs a few years back :\

Glad to hear you figured it out!

Re: Creeping failure to send emails

2009-10-18 Thread tonycd

Weird Epilogue:

Talked to the ATT Tier Two support people (the competent ones they
diligently try to keep you from reaching).

Ultimately, he concluded that for some reason, Thunderbird wasn't
recognizing the presence of my username and therefore was internally
rejecting my username/password combination.

Eventually I correctly guessed why. For some reason, a few years ago
another Tier Two rep fixed a connection problem by changing the
username in my email client from (myname)@sbcglobal.net, to (myname)
%sbcglobal.net. Counterintuitive to me, but it worked with it and it
didn't work without it.

Now, for whatever reason, it didn't work until it was changed back to
@. Apparently Thunderbird looked for the properly spelled username
with @, didn't find it, figured the username was incorrect, and
generated the boilerplate error message.

At least for the moment, instant fix.

Thank you again, Dan, for all your help. The transcript of this
discussion speeded the diagnostic process considerably.

Gracias,
Tony

 Ok

 It's not Thunderbird - if the prefs etc were foo, it would be failing
 all the time.

 It's not your DNS - that translation (the dig) was good.

 It's not your path to Yahoo's servers - the traceroute is ok.

 That brings us back to the original error message:

 The message could not be sent because connecting to SMTP server
 smtp.att.yahoo failed. The server may be unavailable or is refusing
 SMTP connections.

 I just hit that SMTP server cluster directly, using telnet.  Most of
 my attempt succeeded in connecting and getting the server's first
 response.  But quite a few failed!

 So the problem is Yahoo's server is refusing connections now and
 then.  This is the type of thing that Yahoo should have noticed and
 fixed fairly quickly. but  sigh.  At this point the best thing to
 do would be for you to send a message to your ISP.  Give them that
 error message.  Tell them that DNS lookups and a traceroute seems
 fine - that the problem is that the server itself is not always
 responding.  Because this is a contracted/outsourced service, it may
 take a while to fix...

 IN the mean time You might want to switch to a more reliable
 provider.  My fav these days is Gmail...

I actually have my gmail account read (via POP) my mail from my Yahoo
account. That way I didn't have to immediately track down each source
of email and change the email address on the sender's site. I *am*
doing that, but very gradually on a when I can get to it basis.

FWIW, aside from the occasional accessibility glitch that all cloud

I worry a lot less about backing up with google than I would if the
data were on one of my machines.

Since moving to gmail my email is actually a lot more available to me
since it's not on a single machine that I'd have to use to access it.
I guess Google's servers are occasionally unavailable or, more likely,
slow. But that doesn't happen often enough for me to think about
managing my own email storage again.

But, yes, that mess with Sidekick is the worst nightmare of anyone who
uses a cloud based service. OTOH, it sounds like the Sidekick customer
data loss was the proverbial perfect storm of incompetence and
neglect. (Or worse).

I have ATT DSL, connected by wire to a Quicksilver running Tiger and

Thunderbird for email.

In recent days, both machines are having increasing trouble sending
emails. At first, you'd fail on the first one or two attempts and then
succeed. Now, you fail about 6+ times before a success. (Receiving,
and browsing, both work fine.)

I'd think this suggests a corrupt prefs file, but I'm hesitant to
start wiping out preference files left and right, since I'm frankly
not sophisticated enough to restore them. I do have a recent backup of
both machines' configurations on an external hard disk, but I also
have better ways to spend my Sunday than bumbling around ignorantly at
the business of incompetent file replacement.

What's this sound like to you eminent minds out there?

Sometimes ISPs require that you collect email before they allow you 
to send any.

This is done to reduce the possibility that spammers can broadcast 
their wares through your ISP's network connection.

 smtp.att.yahoo failed. The server may be unavailable or is refusing
 SMTP connections. Please verify that your SMTP server setting is
 correct and try again, or else contact your network administrator.

 Sounds like a network or server problem.

 Make sure the name of the server is smtp.att.yahoo.com, not just
 smtp.att.yahoo.

The POP server is for *receiving* mail.

SMTP is for *sending*.

It's the SMTP server you need to check -- smtp.att.yahoo.com

Re: Creeping failure to send emails

2009-10-11 Thread tonycd

Thank you for straightening me out on that, Dan. Thank goodness
somebody here knows what they're talking about, since I certainly
don't.

The SMTP address is exactly as you specified it: smtp.att.yahoo.com .
What would be the next most likely suspect here?

Thanks again,
Tony

Double check with your ISP that the address smtp.att.yahoo.com is 
still the correct server.

If it is, then next we test the connectivity.

Launch Terminal (it's in /Applications/Utilities).  Copy these two 
lines together and paste them into the Terminal window:

dig smtp.att.yahoo.com
traceroute smtp.att.yahoo.com

The dig should run quickly, but the trace may take a while.  If it 
gets stuck repeating lines like this:
12  * * * then just hit ^C (control C) to stop it.

Then copy the whole mess and paste it into your reply here.
