Hello,
ok so I have my own server running centos7 and cPanel 94
I had setup csf and was using my own cPanel email smtp to send emails on one of my sites. Seems my isp has some bad ip’s (not mine) but they are getting rejected @outlook as spam because Microsoft banned the whole ip block of my isp
So I opted to use postmarkapp.com for email service. But with SMTP_BLOCK
ON, the emails don’t work. if I turn that off it works. Any work around so it’s not off for all domains on my server and can add my one domain to the ok list or another way to get emails to work. Using port 25 or 587 without sacrificing server safety. I want to have safe measures but also want my emails to work.
Another issue I’m seeing is all emails are on greylist. all my emails from my site are added to greylist now, and wait time to send is around 20-30 mins. How to avoid greylist. There is not 1 ip but many ip’s postmarkapp sends from so trying to get a list from them is not possible to whitelist.
Is it safe to turn off greylist or if I check mark allow emails with good spf will this still be safe? Or another way to make sure all emails from my domain are not added to greylist ?
no one else is using this server. All domains belong to me just FYI.
Thanks so much for any help
