Elmah sends error mail on development server, but not on production

Question

Hi,

I am trying to set up Elmah so that it sends me an e-mail when a new error occurs. This works fine on my development server, but on the production server no e-mail is sent. The exception is logged on the production server, it's just the e-mail that does not get sent.

Here are my elmah configuration settings:

<elmah>
        <security allowRemoteAccess="yes"/>

        <errorMail
     from="<MYGOOGLELOGIN>@googlemail.com"
     to="<MYGOOGLELOGIN>@googlemail.com"
     subject="ERROR From Elmah"
     async="false"
     smtpPort="587"
     useSsl="true"
     smtpServer="smtp.gmail.com"
     userName="<MYGOOGLELOGIN>@googlemail.com"
     password="<MYGOOGLEPASSWORD>" />


</elmah> 

I've tried different mail servers, both local and remote, and I tried both synchronous and asynchronous mail sending but to no avail.

Now I don't have the slightest idea how to proceed (apart from debugging Elmah on my production server, which seems like a lot of effort to set up). Please help!

Thanks,

Adrian

Edit: I might also add that I tried switching off the firewall on the production server, but that did not make any difference either.
