localzuk Posted January 23, 2020 Posted January 23, 2020 So, I've just found that Google had quarantined about 500 emails in to our domain, but it doesn't say *why* it did it. So, can anyone explain what criteria it uses to block these emails? Most of them are emails from our helpdesk to our users. We have SPF records in place covering their SMTP server being allowed to email as our domain, as well as the Google servers, so SPF shouldn't be the cause. I'd like not to have to constantly release email!
caffrey Posted January 23, 2020 Posted January 23, 2020 Do you have a spam policy in place on the gmail service ? (Apps - G Suite - Settings for Gmail - Advanced settings) I usually find the quarantine gives a reason. Have you had any IP's changed recently ? E.g. SMTP relay allowed IPs
localzuk Posted January 23, 2020 Author Posted January 23, 2020 OK, so I worked through this with someone from Google. It wasn't saying *why* it was blocking things. All the emails were passing SPF and DKIM. Turned out to simply be the default spam stuff - our helpdesk software generates really long URLs for its "how did we do" stuff. That's the only thing they could figure was being caught. We've whitelisted it now
