I'm not having any luck setting up a GMail account for the SMTP Server Settings in a DNN 4.05.03 installation.  I've allowed POP in the gmail account and tested it from Outlook successfully.  I've tried several configurations in the SMTP setting section (Host > Host Settings tab) without any luck.

For the SMTP Server and Port textbox, I've tried both smtp.gmail.com:465 & smtp.gmail.com:587

I've tried about every combination for the Authentication and Enable SSL selections, and I've copied the username and password exactly.

I've also contacted my host and they say that they don't block these ports.

Has anyone done this successfully and know what the settings are?

Thanks,
David

Here's the error I'm receiving:

afaik DNN will pull the SMTP settings from the database/host settings, not from the web.config file

UPDATE:  I just setup another DNN installation, same host, same DNN version (4.5.3).  I tried using the GMail address for SMTP settings and now I get the following error:

"The specified string is not in the form required for an e-mail address."

I even copied over the same exact email address from the other (successful installation).  (the address is myname@gmail.com and it includes no punctuation in the name... it's the most basic email address possible.)

Has anyone seen this error before and how it might be resolved?
