Sorry, but long... (names have been changed)... any suggestions would be greatly appreciated (and constructive criticism humbly accepted).
Environment: Mixed Mode with 3 E5.5 Servers and 5 E2K servers. e55-mail01 - E5.5 - IMC, x.400 site connector e55-mail02 - E5.5 - mailbox server e55-mail03 - E5.5 - mailbox server e2k-mail1 - E2K - participating in accepting inbound SMTP for entire site e2k-mail2 - E2K - participating in accepting inbound SMTP for entire site umr-msxproto1 - E2K - currently just idling - will be a front-end server umr-msxproto2 - E2K - SRS server umr-msxproto3 - E2K - currently just idling - will be a front-end server --Inbound SMTP mail is flowing through e2k-mail1 and e2k-mail2 while outbound is flowing through e55-mail01.... just a transition state... eventually all in/outbound will be handled by E2K. --e2k-mail1 and e2k-mail2 are configured to send all unresolved e-mail to smtp.domain.edu (Linux Sendmail box)... this is because domain.edu is shared by AD and Linux and we have listserv lists (like [EMAIL PROTECTED]) that are on a Linux Listserv box. Additionally all mailboxes in Exchange have an additional e-mail address of [EMAIL PROTECTED] (besides their primary of [EMAIL PROTECTED]).. this is so mail routed through smtp.domain.edu can route the smtp mail to either a sendmail box or exchange.... for example if [EMAIL PROTECTED] comes in to smtp.domain.edu and he is on exchange, the address is re-written to [EMAIL PROTECTED] ... if he is on the Sendmail box the address is left unchanged. --In E5.5 we have CRs configured with a primary address of @domain.edu and a forwarding address of @domain.edu (before my time and I'm unsure as to why it's this way)... messages addressed to these CRs flow out the IMC on e55-mail01 Problem: If I address a message to [EMAIL PROTECTED] this will route through smtp.domain.edu (sendmail) and into e2k-mail1 or e2k-mail2 (E2K)... these servers will not find this address... they will then (because they are configured to) route this to smtp.domain.edu (passing it through e55-mail01 on the way to smtp.domain.edu).. this is a mail loop and fills the transaction log drive on e55-mail01.... summary: 1. email to: [EMAIL PROTECTED] (not a valid address in exchange) 2. smtp.domain.edu (sendmail) receives it from the internet 3. e2k-mail1 (or e2k-mail2) receives it from smtp.domain.edu 4. E2K box does not resolve the name and so forwards it to smtp.domain.edu via e55-mail01 5. smtp.domain.edu receives it from e55-mail01 and sends it to e2k-mail1 or e2k-mail2 ... goto 4 The reason that I have 'Forward all mail with unresolved recipients to host' configured (properties of 'default smtp virtual server' then 'Messages' tab) is because we have listserv addresses like [EMAIL PROTECTED] that are hosted on a Linux Listserv box.. without this configured e-mail to the listserv lists bounce for users on E2K. Additionally, when and E5.5 mailbox sends to a Custom Recipient (configured as above), the message is sent out the E5.5 IMC... a mailbox on E2K sends to this same CR and gets NDR stating " A configuration error in the e-mail system caused the message to bounce between two servers or to be forwarded between two recipients. Contact your administrator. <e2k-mail1.domain.edu #5.4.6> " Questions: 1. Is there a way to tell E2K to forward the @domain.edu messages that don't resolve to smtp.domain.edu without using the above configuration? 2. Is there a way to tell E2K NOT to forward @msx.domain.edu messages when they don't resolve? Things I'm after: 1. Mail from exchange to @domain.edu - if addr matches a primary or proxy address, deliver locally, otherwise send to smtp.domain.edu 2. Mail from exchange to @msx.domain.edu - if addr matches a primary or proxy address, deliver locally, otherwise bounce 3. Mail from exchange to any other domain - send to smtp.domain.edu 4. Mail from exchange - if addr matches a primary address for a custom recipient that is forwarding to @domain.edu that is not resolvable locally, send it to smtp.domain.edu, do not treat it as a bounce. (Right now, it bounces on e2k, but on E55 it dumps it out smtp.domain.edu.) 5. The two e2k SMTP hosts should accept mail only for @domain.edu or @msx.domain.edu (I believe we have this functional with recipient policy and the setting for relay.)
