I've been reading more in the mimedefang-filter man page, and I'm unclear regarding some aspects of the section titled RBL LOOKUP FUNCTIONS. I'm just not very good at Perl, I'm afraid - I'm an old C hack, so program flow is not an issue, but the syntactical differences keep tripping me up.
Anyway, the man page is unclear on WHERE (in mimedefang-filter) the relay_is_blacklisted_* functions should be placed. I would think that filter_relay would be the place, but I'm not sure. Could someone clarify that? I'm also looking for some example code using relay_is_blacklisted_multi_count, including how to construct the array of RBLs to pass to that function and how to properly evaluate the return value (for example, to REJECT with X or more "hits" but not trip over SERVFAIL or NXDOMAIN). Additionally, I'd love to use the md_check_against_smtp_server function, but I'm not sure I can. In my environment, where I host a number of Domains, the MIMEDefang server could relay to any one of 4 other servers. That is, "[EMAIL PROTECTED]" might have his mailbox of "server1.domain1.tld" while "[EMAIL PROTECTED]" has her mailbox of "server2.domain1.tld" and "[EMAIL PROTECTED]" has a mailbox on "server1.domain1.tld". Sendmail deals with this thru the use of mailertable and virtusertable. Do I need to employ stream_by_recipient ? Or should I use the SOCKETMAP functionality (I do have sendmail v8.13.4) to have MIMEDefang query virtusertable and mailertable? For that matter, as MIMEDefang looks at these E-Mail addresses, is it seeing them *before* or *after* sendmail has run thru aliases, virtusertable, and mailertable? Does anyone ever have an environment where they host multiple Domains across multiple interior servers? Also, does the SMTP server against which the "check" will be done need to support VRFY? If not, are there any of the usual anti-SPAM settings in sendmail (e.g. needhelo) that should be avoided so that MIMEDefang can place its query? Thanks again to the MD community for the assistance.
