system.net.mail - email sending no longer working

Hi,

Previously on my web app I had a contact page that would send an email to me with all the filled in values from the user. The email would be sent with the FROM address the user put in, so when I received it I could reply back to them. I had this working for years, and now all of a sudden it errors out.

I get the following error. Please note I was using System.Net.Mail, but changed to a component to try and debug.

I'm wondering what would cause this error to happen suddenly? Perhaps a configuration change in IIS ? What would be a good work around to this ? Is it possible to maybe email from my own domain, but specify a different ReplyTo address?

Thanks,
mike123

Destination Full means exactly that. You're sending to an address where the mailbox will accept no more messages. You can't fix this, the problem is the recipient needs to read their mail and empty their mailbox.

Hi Jeff,

Thanks for the lightning quick reply, but sorry I forgot to include this part. I have emptied the mail box, it is definately not full. Also to make sure it wasnt a server side mail problem I also tried sending to other email addresses that also were verified to not be full.

I was thinking it might have something to do with the relaying ? I can paste mail logs if that might help ?

Thanks again,
Mike123

anybody have any other thoughts on this ?

much appreciated
