    Hi ,

    Thank you for reaching out to Sophos Community.

    You can filter out smtpd_main.log events with sender/recipient address.

    or you can also filter out quarantined logs under 'Mail logs' and hover the mouse on Status to get the reason.

    hello Yash,

    i have created an email policy and add my 4 domain in it, having only issue with 1 domain. firewall is configured in MTA mode.

    i have checked that policy is marking outbound email for that domain as spam, what might be the reason of that.  as users were facing issue so i created a ticket and support guy told me that due to bulk email from that domain might be this is maked as spam, for outbound email he created a by pass antispam policy for that domain , by doing this now outbound emails are getting though, 

    can i verify that my bypass policy is wokring??? can i cross check from logs???

    now facing issue with few inbound emails, due to spam reason they are qurantined, what i m doing, from qurantine email i donwload that email and submit sample to not-spam@labs.sophos.com. 

    is this the right way i am doing.

    You can either check the email log event in the log viewer & check its conntrack details or may also check smtpd_main.log events to get detailed information.

    This is the correct way to submit samples to Sophos Labs team.

    Submit samples of phishing, spam, or false-positive emails to Sophos Labs
