Note, however, that expansion of long local aliases can be very
fragile. If you list "$myorigin" in "mydestination", the delivery
to all the users needs to succeed, or all are retried again if even
one delivery fails (mailbox over quota, ...).
It is far better with long aliases to use indirect delivery:
alias: :include:/list/of/members/in/a/file
This form is always delivered indirectly, with a new queue file
for the expanded list of recipients.
If your user accounts are not "local" ($myorigin is not listed
in $mydestination) and aliases are only uses for lists:
mylist: user1, ..., userN, continue-1@localhost
continue-1: ..., continue-2@localhost
continue-2: ...
then delivery to the users is automatically indirect, but the
continuations are processed recursively, and there is no problem.
However, with large lists you also REALLY SHOULD have an "owner"
alias:
owner-mylist: someone
Finally, I recommend handling list expansion via virtual(5) not
aliases(5). As much as possible, use aliases(5) only for pipes to
commands and ":include:".
