Hi Wayne,
Yes, many dinners have been burnt or not cooked at all {or in my case, let
the kettle boil dry :-} because of the Mail Action and multiple SMTP sends.
>From what I understand, the Mail Action (for both T2K and Witango v5) has
some limitations in it's ability to communicate SMTP transactions -
particular when the SMTP Server is overloading and needs the Requests to be
queued by the sender (naming the Mail Action).
The new <@EMAIL> Metatag in v5 has improved support - I would recommend
checking it out.
A more short-term solution might be to replace the Mail Action with a File
Action (if the SMTP Server is on your LAN), and write your email content to
a simple text file (with Email compliant headers and such) to the SMTP
Server outbound folder.
For IIS' SMTP Server, this is "C:\Inetpub\mailroot\Pickup"
I use this myself, and many others have reported good success with large
amounts of mail.
Most SMTP folders work on a similar "folder" method, where the Server just
monitor's what been dumped into certian folders and then performs actions
based on the folder type. The files will just wait there until they are sent
one-by-one.
I would check the documentation of your SMTP Server, and see what it says
about the folders. Try sending an email through it and capture a copy of it
(from whatever outbound folder) - then open it in a text editor to see what
the format should look like.
Hope this helps. Cheers.........
