The user "vahid" of course exist on the system, that is me, but the
senders often get the following error in a bounced back email.
Can anyone explain why emails bounce only sometimes, if qmail was not
configured correctly, all the mails to that user would bounce but that
is not the case. I am using Qmail on Solaris 9 with system's
getpwnam().
Thanks,
Vahid.

Hi. This is the qmail-send program at MyDomain.COM.
I'm afraid I wasn't able to deliver your message to the following
addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<vahid@mydomain.com>:
Sorry, no mailbox here by that name. (#5.1.1)
