Hi, Is it possible to rewrite an email address that contains invalid characters?
Example: Rewrite ":u...@domain.com" to "u...@domain.com" -- stripping of the leading ":" (colon). I read through the Postfix Address Rewriting README [1] but did not find a hint. Source routing looks close but that's not it. Using header_checks [2] with REDIRECT is also not very useful because I have to create such an entry for every possible email address. Background info: We're currently having a problem with Zimbra Collaboration suite 6.0.5 and Thunderbird Lightning 1.0b1. Calendar invitations from a customer contain an empty CN= field in the organizer and attendee fields as follows: ORGANIZER;CN=:MAILTO:organi...@exchangeuser.com ATTENDEE;ROLE=REQ-PARTICIPANT;PARTSTAT=NEEDS-ACTION;RSVP=TRUE;CN=:MAILTO:be...@zimbrauser.com ATTENDEE;ROLE=REQ-PARTICIPANT;PARTSTAT=NEEDS-ACTION;RSVP=TRUE;CN=:MAILTO:other...@zimbrauser.com The bug is, that when accepting/declining the calender, the email parsing is wrong and wants to send an email to :organi...@exchangeuser.com (yes, with the leading colon). This email address is rejected on the customer's email server. I thought about using Postfix on our outbound SMTP gateway for stripping off the leading ":" from the destination address. Thanks in advance. Best regards, Bernd [1] http://www.postfix.org/ADDRESS_REWRITING_README.html [2] http://www.postfix.org/header_checks.5.html
