Please do not interpret this as a spam on your comments, but most ISPs are now requiring SMTP AUTH on all sent email. When combined with NO MAIL RELAYING its a definite way to prevent spamming from being routed thru your servers. AT&T, MSN, SBC/Yahoo/Ameritech, AOL, and many others have battened down the hatches and required all of their email users to, in one way or another AUTHORIZE before they will accept any mail for delivery from them.
Yes, you will have a lot of clients calling and telling you they can't send email. Most of those calls will be because they didn't read the notice(s) you sent out telling them that this was now going to be a mandatory change and not something they could ignore. Once you make the change and deal with the calls, it will never have to be done again. In my humble opinion, it should be made the defacto standard for all email servers. That would go a long way to prevent a lot of the spamming that is clogging both our mail servers and the pipelines that feed them.

OK, so we all aren't as bright and as experienced as you guys and maybe we don't spend our waking hours with iMail. I figured I would just try to ride in one the shirt tail of the other query but didn't expect to be tarred and feathered for it. >yes. set SMTP security to "no relay" or "relay for addresses" I suppose most of you folks must have iMail servers in dedicated environments intranet environments. Would you like to explain to me just how you would apply the latter with a lot of remote users who have transient IP addresses? >This list has been through your situation 1000's of times. Please check >the archives. Yes, and you probably will have to go through it many times more. I knew this had been on the board before. I guess that our only recourse will be to use the SMTP AUTH as much as I hate the thought of what I am going to have to go through in the process. But seeing the probing that is going on by outside hackers trying to find legitimate user accounts to forge it is clear it is only a matter of time before we have major problems. Has anyone had the experience of taking 500+ email accounts on 50+ sites and making them all switch over? I know that what we will have to do is advise all of them to change their setting in all the email applications and then turn the switch. The day we do I am sure I will get endless calls from the clients who didn't bother to read the email advising them of the change telling me they can't send email.
