Hi,
My ISP is not supporting smtp relay through one account, so i need to configure smtp relay to work with each user's username and password.I mean on relay servers you have one main username and password like "bounce@mysite.com:123456" and all smtp traffic works through this e-mail, unfortuantely my ISP company does not support that.
I've found 2 articles for it viewtopic.php?t=21255 and viewtopic.php?f=13&t=37055&start=10, tried both on fresh installed Zimbra 8.5 - Ubuntu 14.04 but on every try i get this error "address resolver failure", computer can connect to internet and can ping to my isp's smtp server, any idea how i can fix this error ?
