Hello,

I have a problem with my postfix+mysql+maildrop (probably caused by maildrop) Today i found an undelivered message in mailq from root to bin! Just i tested what's happend when i try to send a message manually from root to bin and maildrop refuse to deliver it.

[root@dinu biiiiin]# mailq -Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient------- 03EC820A69 316 Mon Nov 18 17:37:25 ro...@test.ro (temporary failure. Command output: /usr/local/maildrop/bin/maildrop: Invalid user specified. ) bi...@test.ro

-- 0 Kbytes in 1 Request. [root@dinu biiiiin]#

And in my syslog appear: Nov 18 17:37:45 dinu postfix/cleanup[5838]: 03EC820A69: message-id=<2002...@ns1.test.ro> Nov 18 17:37:46 dinu postfix/qmgr[5666]: 03EC820A69: from=<ro...@test.ro>, size=316, nrcpt=1 (queue active) Nov 18 17:37:46 dinu maildrop[5845]: Invalid user specified. Nov 18 17:37:47 dinu postfix/pipe[5844]: 03EC820A69: to=<bi...@test.ro>, relay=maildrop, delay=21, status=deferred (temporary failure. Command output: /usr/local/maildrop/bin/maildrop: Invalid user specified. ) Nov 18 17:37:48 dinu postfix/smtpd[5837]: disconnect from dinu[127.0.0.1]

The problem is this message remain in mailq and is not returned to the sender. If i use transport=virtual, all messages like this are returned to sender informing that is not a system account wtih this email address on this server.

This is a problem, because someone can write a wrong email address and NEVER will be informed that the mail can't be delivered succesfully!

Can somebody tell me how can i instruct postfix (or maildrop) to return an email to sender informing that : no such mailbox here with that name, and also not to put this email in mailq?

Another question: how can i erase forever undelivered messages from mailq?

Any help will be appreciated!

Regards, Alex
