    Default [SOLVED] Not able to sendmail with Ms.Outlook at home.

    hi,

    I setup zimbra server version 5 on RHEL5 server. Both software are 64 bits.
    Everything is working fine if I work at office. I able to send and receive mail with my outlook 2007.

    But when at home, I not able to send mail and got error. Anyway I able to recieve mail.

    "Task-sending" report error (0x800CCC0F)

    my zimbra mail server is setting up behind a firewall and i use firewall to publish the server to internal..... Port 110, 25, 80 will be forward to my zimbra server.

    my MTA setting is 127.0.0.0/8 192.168.0.0/24


    I need help to solve this problem as my users will connect back from home, they need to be able send and receive mail when they are at home.
