Dear List,
Is there any performance related or other concerns if I try to send
mail to a group containing thousands of users (say 8000) using the
alias map? In case we want to use alias map for this, then which type
of db we should use?
With regards,

There will be no performance issues per se, apart from the fact that
postfix will have to explode one message into 8000 at once.
If you're determined to do this, I would suggest at least 2 levels of
alias, with the first expanding to a few dozen groups, and each group
expanding to a few hundred addresses.
You will have better control that way.
Also, I would use virtual_alias_maps instead of just the local aliases,
since it is much more flexible.
However, a mailing list manager (MLM) is obviously the better choice for
this.
