I *never* said it was easy. I only said it should be possible on most platforms. Also, I never said it was even necessary. Thanks for the tech discussion, I even feel my neurons getting out of lethargy! :) On Jun 18, 2010 9:47 AM, Victor Duchovni victor.ducho...@morganstanley.com wrote: On

Jose, Unfortunately, looking at another server OS doesn't help me to find the answer to this question. But thank you for the suggestion. I am still trying to find out how Apple OS X Server 10.6.3 (Darwin Kernel Version 10.3.0), running Postfix 2.5.5, Amavisd, ClamAV, SpamAssassin, Dovecot, and

Charles, Just for clarification, and remember, I am very new at all of this. Postfix is requiring SASL Authentication. I have not listed any user names or passwords anywhere except in Apple Open Directory as User Short Names for use with login to network resources. Postfix seems to reference

Viktor, You said: You need correct mappings in smtpd_sender_login_maps, mapping each sender address to the correct SASL login. Does that mean that Postfix will not pull the User Name and Email address from the Open Directory? I had assumed that it was already pulling the User

Thank you. I will give that a try. Can anyone answer the question about how SASL is able to authenticate Users with their Passwords stored in Open Directory, but not pull their Email addresses? On Jun 15, 2010, at 3:14 PM, Jerrale Gayle wrote: On 6/15/2010 12:33 PM, Andrew G. Grant wrote:
