Are you talking about DH’s Squirrelmail implementation or another locally installed web mail server?

If it’s DH’s Squirrelmail, you might want to contact support as if you can log in, your user should exist. (I think that’s what the message is saying). If you include the information you’ve posted here, I’m sure they can help.

i am referring to DH’s Squirrelmail, how would i go about contacting support? thx.

I suggest you ignore the mXXXXXXX format for usernames. Just go with YOU@YOURDOMAIN.COM for sending, receiving, and logging in to check your mail.

Or did you already do that? If so, then how new is that mail account? Has it ever worked? Can you send to that address from outside, such as Gmail or Yahoo?


Last option on the control panel at

(that really is a strange message and I don’t think you can change things to make it work like that - unless you maybe deleted the mailbox while logged into squirrel mail…)

(or they could just magically reply like he did above. But it’s not terribly common for them to do that! Well, it never USED to be common.)

I created the email about an hour ago, I am able to log into DH mail client and send mail to other DH email accounts I have as well as to both Yahoo and Gmail accounts that I have.

I only have an issue when trying to reply back to this email account.

My first guess is to give it time. Addresses tend to take an hour (or more) before it completely spreads across all the DreamHost servers.


thanks very much, i have opened a support ticket.

thanks for the feedback, i have opened a support ticket but i will wait on this until tomorrow.
