Zimbra 6.0.7 uses a wrong "MAIL FROM" command, sending emails with external accounts
Hi all, I post this thread because I'm facing a problem sending emails from external accounts.
I have one zimbra account, email@example.com which has an external account configured firstname.lastname@example.org.
I need zimbra to relay mails sent by email@example.com to the ISP's MTA (configured as postfix's relayhost) and the one sent by firstname.lastname@example.org to be relayed through another MTA (configured as sender_dependent_relayhost_maps in postfix's main.cf).
Unfortunately the mechanism does not work because if a login as email@example.com and I send an email as firstname.lastname@example.org, the message has still the from field containing email@example.com so it will be sent through the default relay host.
Could someone explain me why I get this strange behaviour?
Could it be a known issue of my Zimbra release? I use zcs-6.0.7_GA_2473.UBUNTU8_64.20100616212156.
