mail usage

AreshAreshi

Hi,

We have for sometimes now move to Office365, but when get a daily report from utm, under the mail usage I can see 7 or 8 mails! if I go to the mail manger I cannot trace those email address!

We dont have any exchange server behind the UTM.

What this means?

 

Thanks

    What do you see on the SMTP tab of Mail Manager?

    Why is the SMTP Proxy enabled if you're using Offfice365?

    Cheers - Bob

    We just left it on for the time being, our mail license will expire soon and we will disable the proxy.

    The strange part is when I check the mail manager I can see only the daily reports that utm sending us.

    Question remaining is what are those emails? the senders are all known to us.

    You need to disable the SMTP Proxy while you still have a license that allows you to access that part of WebAdmin.

    Thank you Bob,

    We will do that.

    But before doing so, we have a virtual SMTP in LAN that our websites using it to send newsletters, and when I check the relay section of the mail protection see this smtp server there,
    Now when we disable the smtp proxy, do we need to create a firewall rule to allow smtp connection from that virtual SMTP to out side? currently all out going traffic is allowed.

    Thanks

    Is the SMTP Proxy running in Transparent mode, or does your newsletter mailer use the UTM as a smart host?

    The SMTP porxy is in simple mode. the virtual smtp server does not use the UTM as smart host. we have just added the smtp server to the Host-realy section of utm

    Surely there must be some where that we can see from where those mails are beening send right? in the mail manager I cannot find nothing.

    If the SMTP Proxy is not in Transparent mode and your mailing server does not use the UTM as a smart host, the emails are not being relayed off the SMTP Proxy.

    Thank you again for your reply,

    Yes we dont use SMTP in Transparen mode and the virtual smtp dons not use the UTM as smart host.

    Dont you think a bit strange that sometimes we see mail usage at utm!!? the last mail usage is from last Sunday.

     

    Thanks

    I would expect to see activity every time the UTM sends a notification.

    Cheers - Bob
