Hi Imar,

I have a site with some random users. Each user is able to set up a group. I want to set up a page where he can email his group members.

Question: I host my site on Godaddy.com. Can I allow the FROM: field to be the actual email of the user (e.g., he has a @yahoo.com email account)?

I have things set up so that I can send emails from my site to users. But right now, all the emails have [email protected] as the sender (which is set up as a valid email account on host account), which goes through. Must the Sender always be a valid account on the email service being used?

I guess this makes sense for security (protect vs spamming reasons); otherwise, ppl can send mass emails and make it appear to come from legitimate emails (spoofing), right?

Anyways, I suspect this and wish to confirm. Thus, allowing me to understand what is and isn't allowed with email sending.

Thanks,

Hi there,

It depends. Some outgoing mail servers just accept whatever From address you're using. Others reject the message completely, and yet others overwrite it with the address that belongs to the account. Looks like in your case you fall in the third category. Could be a GoDaddy security setting so if this is important, find another host ;-)

Have you tried setting the From address explicitly in code or in the web.config?

Also, take a look at the ReplyToList property of the MailMessage: http://msdn.microsoft.com/en-us/libr...plytolist.aspx
That way, the From may not be what you want but replying to the message gets you the proper address.

Cheers,

Imar
