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]')
