I've been happy with Fastmail as a GMail alternative. Been slowly moving my logins and usernames from one to the other. Only (rather significant) complaint is that since 2018, they're affected by Australia's encryption backdoor bill.
Would you please be able to share a source for the encryption back door? I assume they can access email using the usual court order process in AU but worried this will turn into a free for all like ISP data retention..
I made the move to FastMail about 4 years ago, would hate to change again, is such a pain. Luckily I did opt for my own domain name at least which should make those changes easier if I do it again.
The legislation specifically prohibits authorities from requiring the creation or retention of any systemic weaknesses or vulnerabilities, or "any act or thing that will, or is likely to, jeopardise the security of any information held by any other person", other than the individual(s) targeted by the warrant.
I think the law is over-reaching and lacking in sufficient transparency, but I don't really think it would allow anything like the common understanding of "encryption backdoor"?
