Postfix access file validation

no flag
Matt K

I am trying to test if my postfix access files are working properly (to block spammers) but I am getting different results based on if I create a regular expression access file or a hash access file.

Here is my regular expression access file:

/@spammer.com$/ DISCARD

Here is my hash access file:

spammer.com DISCARD

I am testing their validity using the postmap -vq command but getting differing results.

Regexp:

$ postmap -vq [email protected] regexp:/etc/postfix/sender_access_regexp
postmap: name_mask: all
postmap: inet_addr_local: configured 4 IPv4 addresses
postmap: inet_addr_local: configured 4 IPv6 addresses
postmap: dict_open: regexp:/etc/postfix/sender_access_regexp
postmap: dict_regexp_lookup: /etc/postfix/sender_access_regexp: [email protected]
DISCARD

Hash:

$ postmap -vq [email protected] hash:/etc/postfix/sender_access
postmap: name_mask: all
postmap: inet_addr_local: configured 4 IPv4 addresses
postmap: inet_addr_local: configured 4 IPv6 addresses
postmap: Compiled against Berkeley DB: 5.3.28?
postmap: Run-time linked against Berkeley DB: 5.3.28?
postmap: dict_open: hash:/etc/postfix/sender_access

The regular expression access file reports a DISCARD but the hash access file does not. Is my hash file not working, am I not validating the files correctly?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
