Well, for SMTP, "domain equivalent" addresses have square brackets
around them:
postmaster at 127.0.0.1 Illegal
postmaster@[127.0.0.1] Good
Which might work for port numbers using something like:
[127.0.0.1]:25
[::1]:587
Until such time IPv8 introduces [] into the address specification.
Sendmail uses a similar format with a prefix for IPv6:
FEATURE(`msp', `[IPv6:::1]')
