On the old and new server we use virtual domains.

What are you using to do the authentication? And, when you mean logging in do you mean to check mail (IMAP/POP3) or to send mail (SMTP AUTH)? I am using dovecot. I mean IMAP/POP3 and SMTP. It's really not a big deal if I need to use the @ sign, I just figured if I could do both it would ease the transition. Maybe this helps: http://wiki1.dovecot.org/MainConfig?highlight=(auth_username_translation)
Blackhole Messages
Hello all,
I have a server running Postfix 2.5.1 on Ubuntu LTS. Over the years I have run
many Postfix servers but this is the first time I have a problem that I just
can't seem to find much information about.
Every now and then in the logs I see a message such as this:
Feb 13 14:37:37 lnxsrv01 postfix/local[19279]: 6A861302508:
to=:blackhole:@lx.x.com, orig_to=tanzeel...@x.com, relay=local,
delay=0.49, delays=0.23/0.18/0/0.08, dsn=5.1.1, status=bounced (unknown user:
:blackhole:)
In this case it is spam that has been rejected but in almost 8 years of using
Postfix I have never seen this before.
Here is the output from postconf -n
alias_maps = hash:/etc/aliases
append_dot_mydomain = no
biff = no
broken_sasl_auth_clients = yes
config_directory = /etc/postfix
home_mailbox = Maildir/

You accepted it, then sent a bounce. Ok, That's what I was thinking as some of the hosted domains have been migrated from another server recently. but in almost 8 years of using Postfix I have never seen this before. Here is the output from postconf -n You have munged domain names, looking inconsistent at that, so if your question pertains to mail routing, it is not possible to help you. I can guess what might have happened. You got spam for this orig_to=tanzeel...@x.com, and it was rewritten (perhaps by alias_maps; perhaps by virtual_alias_maps) to this other to=:blackhole:@lx.x.com address. That munged domain is in mydestination (although your munging did not show that), and there's no local user nor alias called :blackhole:. Why this :blackhole: result? You'd have to tell us. The server has been setup with Virtualmin to hande all virtual hosting but oddly the other Virtualmin servers never displayed similar messages in the logs. Maybe blackhole has something too do with Virtualmin. In any event I will have to ask them. alias_maps = hash:/etc/aliases mydestination = xxx.xx.com, localhost.xx.com, , localhost myhostname = xx.xx.com myorigin = /etc/mailname sender_bcc_maps = hash:/etc/postfix/bcc virtual_alias_maps = hash:/etc/postfix/virtual Any assistance greatfuly appreciated The problem description was inadequate, but I left in the possibly relevant postconf lines. So I guess it is largely backscatter that is responsible. Time to read the documentation. Many thanks for your help. -Frog
