Problem: Valid email addresses being rejected. Problem appears to be intermittent; difficult to tell most rejections are legitimate. Not found in a hash named virtualaliases.db virtual_alias_maps = hash:/etc/postfix/virtualaliases When the problem has been reported the addresses are found in the file.
Questions: Could the hash file be too large? Is there a configuration error causing this problem? maillog sample line: Oct 10 12:42:42 mg08 postfix/smtpd[23005]: NOQUEUE: reject: RCPT from unknown[207.46.163.XXX]: 550 5.1.1 <aaaaa...@cnm.edu>: Recipient address rejected: User unknown in local recipient table; from=aaaaaaa...@livecnm.onmicrosoft.com<> to=<aaaaaa...@cnm.edu> proto=ESMTP helo=<AAAA-bn1-obe.outbound.protection.outlook.com> Email account is there: [root@mg08 log]$ grep AAAAAAAAA /etc/postfix/virtualaliases AAAAAAAAA aaaaaa...@aaaaaa.cnm.edu Map involved: virtual_alias_maps = hash:/etc/postfix/virtualaliases [root@mg08 ~]# ls -l /etc/postfix/virtualaliases* -rw-r--r-- 1 root root 5053731 Oct 10 12:35 /etc/postfix/virtualaliases -rw-r--r-- 1 root root 10485760 Oct 10 12:35 /etc/postfix/virtualaliases.db [root@mg08 ~]# wc -l /etc/postfix/virtualaliases 107195 /etc/postfix/virtualaliases postfinger output: http://pastebin.com/ZjSBT4cn -- Robert Lopez Unix Systems Administrator Central New Mexico Community College (CNM) 525 Buena Vista SE Albuquerque, New Mexico 87106
