Hi I know it is mushroom season so maybe it is that but the said OS is creating users with firstname.lastname@example.org rather than just user.tld
Also been have an amazing issue with smtp; 554 5.7.1 <******@******.com>: Relay access denied .... on one virtual server. From Gmail etc.
Yet mail for other domains working fine on same server. Googled all and tried all.
IP was listed on blacklists but have grovelled and all seems fine now, it was an IP my ISP gave me.
I am running a home server for the first time behind my ISP router.
Any ideas would be great.
