I will try again with your tips and I will report here.
sorry for hacking this post but I felt instead of initiating new post, I can continue the same. I have implemented suggestions mentioned in post # 71 and it worked without any issue for zimbra webmail but users who are using outlook they started getting below error while sending the mails :
"Temporary lookup failure"
Note : I have mentioned "reject_authenticated_sender_login_mismatch" in main.cf
Any idea why outlook user's got impacted ?
One more thing..I have mentioned below thing in main.cf :
smtpd_sender_restrictions = permit_mynetworks, reject_authenticated_sender_login_mismatch
Do I need to mention permit_mynetworks ???
I have enabled the SMTP Auth on my Zimbra Server (Open Source), email for external domain required password but if i send email to a local domain user through MS Outlook, it is not required password and email delivered to user successfully. Strange Why It's delivered without password!!!!!
Please help me.
I tried to follow your instructions, but unfortunately without success. First of all, I couldn't persist any modification in /opt/zimbra/postfix/conf/main.cf (logged as zimbra). Secondly, the /opt/zimbra/conf/ldap-slm.cf and /opt/zimbra/conf/zmmta.cf don't exist, I had to use ldap-scm.cf instead.
Finally, I don't know how to put the following configuration in use:
proxy_read_maps = $local_recipient_maps $mydestination $virtual_alias_maps $virtual_alias_domains $virtual_mailbox_maps $virtual_mailbox_domains $relay_recipient_maps $relay_domains $canonical_maps $sender_canonical_maps $recipient_canonical_maps $relocated_maps $transport_maps $mynetworks $sender_bcc_maps $recipient_bcc_maps $smtp_generic_maps $lmtp_generic_maps proxy:ldap:/opt/zimbra/conf/ldap-slm.cf
What file or zm command do I need to use?
Thanks in advance.
I see you are using zimbra 8 , please see my notes to configure this here: http://www.zimbra.com/forums/adminis...tml#post250465 .
