I am looking for an email client that will work on XP that when I reply to emails, the From will be who the email was to. I don't want to use OE, because that requires that you set up an account for every address you'd like to be able to make as from.

I want to forward emails from say 20 different addresses to one address, then when I reply to them whoever they were addressed to is who I want the email to say is from when I reply (instead of my main address that all the emails are forwarding to).

Does anyone know what application can do this or if there is a plugin for Outlook that lets me do this?

It's called a keyboard.
When I have to send an email to a company that I have used a spam tracking email addy (nameofco@mydomain.com), naturally I don't want them to have my real email addy, so I just type in the one I made up to use in the first place in the 'from', and 'reply to', fields, even though I am actually sending it from a real one.

Of course what I am doing is legit, and what you want to do is irritating as heck.

How is what I want to do irritating? Instead of replying with a different email address than what the people sent the email to, I want it to be the same. Pretend they send it to webmaster@123.com and the only address I have in outlook is admin@123.com, well I'd rather the from say webmaster@123.com when I reply then change it to admin@123.com (which is what outlook automatically does). I also get tons of emails every day and wouldn't want to type each from manually when I reply, that'd waste a lot of my time. I have a webmail account that does this, but I want a desktop application to handle it.

Oh, sorry, I thought you wanted to send mail to "webmaster@123.com" and have it say it was from "webmaster@123.com"
Outlook does accept email from more than one source, but it DL's it all in one shot, and wants you to chose one "from" addy. That's why I don't use it.
Incredimail does what you want. It DL's the different email addys in to different folders, and you can reply from the addy that recieved the email, but Incredimail, is a big HOG, where a simple email is like 80k or something with all the headers and BS.
There has to be something else that lets you do that, but right now I don't know what it is. I looked at (and tried) dozens of email proggys about a year ago, maybe there are more options now. If I find one, I'll let you know.

Simple. Use Outlook (not Express) and enter nothing in the To: field. Enter the e-mail address you are sending to in the Bcc: field. By default, Outlook will then put the sending e-mail address in the To: field since something must be there. I've done this many, many times and it automatically enters it for you.

Mark, he wants to reply from the addy that recieved the email.
Like say he has three (or more) addresses, 1@1.com, 2@1.com, 3@1.com. He DL's his email, and begins read the ones to 1@1.com, and wants to reply. He wants to reply from the addy that recieved it (1@1.com) Then he will read the ones to 2@1.com, and wants to reply to those emails from 2@1.com, and so on.

Gotcha'. Okay, still Outlook will work but a little fine tuning is needed. You will need to setup multiple accounts to hold each e-mail address. Then create folders for each specific address. So when someone sends an e-mail to 1@1.com, it will automatically move the message (per the Rules Wizard) to a folder you created called 'one'.

Then download the program at this site (it's FREE): http://www.realpopup.it/realaccount/
This program allows you to tell each specific folder in Outlook where to send e-mail FROM. So you then would specify that when highlighting the 'one' folder you created earlier would automatically use the e-mail address of 1@1.com when sending e-mail. You can even specify which signature to use per folder. If you then have a folder called 'two' for the 2@1.com address, when highlighting it and sending e-mail it will automatically send from 2@1.com -- and so on...

This may take some work to setup but overall, it can be done.

Guys -

Thanks for repying but you are not giving me the answer I need. I DO NOT want to have to set up an account in outlook for every address that I want to reply as "from". I basically have a catch-all so anything@mydomain I can download by setting up ONE account in outlook and logging in with something like admin@mydomain and it will get all mail. Then I just want to have one inbox and hit reply to a message and whoever it was addressed to (ie. sales@mydomain) I want it to say that it is from that address when I reply (instead of what outlook does which is make it from admin@mydomain.com, since that is the only account set up in there). I don't want to have to setup folders or accounts or anything for all the addresses that people send mail to, because sometimes people will send mail to an address that I don't have an account set up for. Does anyone know of another program, whether it be Eudora or anything else that does this?????

Yes, so far, it's Incredimail. You can DL mail from tons of pop3's and when you want to reply, it asks you who you want to reply from (or as). You then chose from a drop down list of addys that you entered when you configed it. You can make folders to coincide with the different addys, you use or NOT.
Unfortunately, it is a HOG, and people don't like receiving large size emails that only contain a short note. It doesn't seem to mind compuserve email, where as a lot of proggys won't even open the darn things. That's how I know. A good friend had CS for her ISP, and Incredimail was also the only proggy that would open all the stuff she likes to foward to me.

Hey, it's free to try the darn thing, so go for it.

I just felt it fair to warn you that some people don't like receiving incredimail email.

I hate incredimail. I prefer my mail in plain text. I can't stand all that extra crap im my emails. It is heavily used by the kind of people who send every joke they come across to about 300 other people. It pi$$es me off.
