Hi all,
I've a generic question to all more experienced than me postfix users
here: Is it nowadays (reasonable) possible to run postfix with IPv6
only? E.g "mail.example.com" and "smtp.example.com" with only ipv6
AAAA records in the DNS, no A / ipv4 anymore?
No.
[...]
I'm only not sure if there might be "IPv4-only" email providers out
there, whose emails might not be routed to my "IPv6-only" postfix.
There are many.
Some do not yet have IPv6 service yet.
Some have IPv6 connectivity and address space but no motivation to make
their mail systems use IPv6. There are reasons to avoid sending over
IPv6 and very few if any significant reasons to want to send or receive
over IPv6. If one has a working IPv4-only mail system, adding IPv6 is
pure work for no discernible benefit.
