    Default [SOLVED] Port 25 Issues using Outlook

    Since some ISPs block port 25, we have numerous people traveling or at home that can't send email from Outlook unless they connect to our VPN first or use the web client.

    I finally found some information to modify the master.cf record to add extra ports for smtp traffic, but how do you configure Outlook to funnel email over that new port instead of the default 25?

    In old POP3 or IMAP settings, that was easy, but is there a way using the Outlook Connector?

    If you're using the ZCO, Outlook communicates with ZCS using http(s).
    Both ways, for everything.

    So Outlook doesn't need port 25.

    That's what I thought, but I have people swearing they can't send email...guess it's time to dig a little deeper...

    thanks for the reply.
