This will get the emails. I'm not sure what you mean by 'set to its own variable', since user1@domain.com is not a valid variable name in either shell or awk.
Code:
$ cat env.awk
BEGIN { FS="<" }
/X-/ { E=0 } /X-Envelope-To:/ { E=1; sub(/X-Envelope-To:/, ""); }
E {
gsub(/[ >,\t]*/, ""); # Strip out all junk
# Print any non-blank emails
for(N=1; N<=NF; N++) if(length($N)) print $N;
}
$ awk -f env.awk data
user1@domain.com
user2@domain.com
user3@domain.com
user4@domain.com
user5@domain.com
user6@domain.com

MAILADDR(7) BSD Miscellaneous Information Manual MAILADDR(7)NAME
mailaddr -- mail addressing description
DESCRIPTION
Mail addresses are based on the Internet protocol listed at the end of this manual page. These addresses are in the general format
user@domain
where a domain is a hierarchical dot separated list of subdomains. For example, a valid address is:
eric@CS.Berkeley.EDU
Unlike some other (now obsolete) forms of addressing, domains do not imply any routing, or the existence of a particular host. Simply
because mail may be sent to ``user@somedomain.com'' does not imply that there is any actual host named ``somedomain.com'', and does not imply
a particular routing of the message. Routing is performed by Mail Transport Agents, such as postfix(1), based on policies set in the MTA's
configuration.
Abbreviation
Under certain circumstances it may not be necessary to type the entire domain name. In general, anything following the first dot may be
omitted if it is the same as the domain from which you are sending the message. For example, a user on ``calder.berkeley.edu'' could send to
``eric@CS'' without adding the ``berkeley.edu'' since it is the same on both sending and receiving hosts. Whether abbreviation is permitted
depends on how your site is configured.
Case Distinctions
Domain names (i.e., anything after the ``@'' sign) may be given in any mixture of upper and lower case. Most hosts accept any combination of
case in user names, although there are exceptions.
Postmaster
Every site is required to have a user or user alias designated ``postmaster'' to which problems with the mail system may be addressed, for
example:
postmaster@CS.Berkeley.EDU
Obsolete Formats
Certain old address formats, such as UUCP ``bang path'' addresses, explicitly routed internet addresses (so-called ``route-addrs'' and the
``percent hack'') and others have been used historically. All these addressing formats are now considered obsolete, and should no longer be
used.
To some extent, MTAs attempt to provide backward compatibility for these addressing forms, but in practice many of them no longer work.
Users should always use standard Internet style addresses.
SEE ALSO mail(1)
D. H. Crocker, Standard for the Format of Arpa Internet Text Messages, RFC, 822, August 1982.
HISTORY
mailaddr appeared in 4.2BSD.
BUGS
The RFC 822 group syntax (``group:user1,user2,user3;'') is not supported except in the special case of ``group:;'' because of a conflict with
old berknet-style addresses, not that anyone cares about either berknet or group syntax style addresses any longer.
