Hello,
I've searched the available archives regarding the subject line above and
couldn't find an answer.
Is there a maximum line that the relay_recipient_maps (or in my case inside the
relay_recipients file) can contain? Here is the line: relay_recipient_maps =
dbm:/etc/postfix/domain/relay_recipients
Any real life sample on what is the number of lines in the relay_recipients
file before starting to see system performance degradation (if any)?
Thanks,

Postfix has no built-in limits on file sizes.
With dbm: type, likely hundreds of thousands of entries before
lookups are affected, although rebuilding the file might be
kinda slow. The hash: or btree: type will probably perform
somewhat better if they are available on your platform.
For larger numbers, cdb: scales well to millions of entries.
Consider building postfix with cdb: support if you need large,
fast tables. http://www.postfix.org/CDB_README.html
Many people prefer to use *sql or LDAP when they get past a
couple thousand entries simply for ease of maintenance.
