I have a new install of ZCS8.0.3 on Ubuntu 12.04.
All is good except sending mail to an external MTA, in this case Bluehost's smtp server. I am receiving emails just fine from the mail accounts outside the zimbra. Been searching over the forum for the day and the closest description of my problem is zimbra replaces the "from" address of outgoing mails with the zimbra account name (and local domain) the mail is sent from causing my ISP's smtp server to bounce it back.
I tried setting zimbraSmtpRestrictEnvelopeFrom to FALSE but nada. Followed Flieben's post [SOLVED] Send mails from external account trough Zimbra to the letter but no luck either.
Can someone point me in the right direction.
Thanks in advance!
