Changes to all AT&T/Yahoo/SBCglobal email
article #455, updated 1790 days ago

Learned this today (7/31/2012). AT&T has changed the names of the POP and SMTP servers for all email accounts for,, and several others (a list is below). Some users will immediately find that Outlook or other email software will not send or receive email, until it is reconfigured to match; it is not unlikely that the changes will not affect everyone at once, but will eventually become essential.

Previously, each of the domains below had different server names for sending and receiving; now, they are all the same, for reception (POP) and for transmission (SMTP). POP has to be done on port 995, SSL turned on; SMTP has to be done on port 465, also with SSL turned on.

Send email via Gmail SMTP by VBscript (incl. SMTP auth!)
article #341, updated 2126 days ago

Here is a VBscript which, if edited for your Gmail account and environment, will work well on anything XP, Server 2003, or above. It does not require any additional installations, CDO is an object built in to Windows:

EmailSubject = "Sending Email by CDO"
EmailBody = "This is the body of a message sent via" & vbCRLF & _
		"a CDO.Message object using SMTP authentication."

Const EmailFrom = ""
Const EmailFromName = "My Very Own Name"
Const EmailTo = ""
Const SMTPServer = ""
Const SMTPLogon = ""
Const SMTPPassword = "gMaIlPaSsWoRd"
Const SMTPSSL = True
Const SMTPPort = 465

Const cdoSendUsingPickup = 1 	'Send message using local SMTP service pickup directory.
Const cdoSendUsingPort = 2 	'Send the message using SMTP over TCP/IP networking.

Const cdoAnonymous = 0 	' No authentication
Const cdoBasic = 1 	' BASIC clear text authentication
Const cdoNTLM = 2 	' NTLM, Microsoft proprietary authentication

' First, create the message

Set objMessage = CreateObject("CDO.Message")
objMessage.Subject = EmailSubject
objMessage.From = """" & EmailFromName & """ <" & EmailFrom & ">"
objMessage.To = EmailTo
objMessage.TextBody = EmailBody

' Second, configure the server

objMessage.Configuration.Fields.Item _
("") = 2

objMessage.Configuration.Fields.Item _
("") = SMTPServer

objMessage.Configuration.Fields.Item _
("") = cdoBasic

objMessage.Configuration.Fields.Item _
("") = SMTPLogon

objMessage.Configuration.Fields.Item _
("") = SMTPPassword

objMessage.Configuration.Fields.Item _
("") = SMTPPort

objMessage.Configuration.Fields.Item _
("") = SMTPSSL

objMessage.Configuration.Fields.Item _
("") = 60


' Now send the message!

Command-line SMTP mailer with SSL for Windows
article #160, updated 2140 days ago

For many years there was ‘blat’, the all-purpose command-line mailer for Windows.  However, blat was never updated for SSL, and a great many email providers (e.g.,. Gmail) require SSL.  One can add a second tool called ‘stunnel’ to create a chain for the purpose, but I don’t like to kludge that much. 

For a while I preferred the applet ‘email’, which is part of Cygwin. However, this is not a standalone applet, and there have been other issues. Just now SwithMail came to light for me:

Am testing. So far, it is working very well indeed.
