any limitation on how many entries in relay_domains

Hello,

Im receiving:
554 Relay access denied


on a just a couple (2-3) domains that I have had in relay_domains for
some time now. I have about 2100 domains in relay_domains file and the

only way to fix the above issue is if I postmap the file. I postmap the

file via cron every night. It doesn't matter where the domain is
located in the file (middle or end), the only way to fix it is by
postmaping. This doesn't happen all the time but once every two weeks
or so.


Is there any limitations or cause for this to happen?


Im running postfix 2.2.8 with Berkeley DB 4.2.52_3 on FreeBSD.


thank you for your time

That's pretty weird that it's always the same 2-3 domain names.

You can verify the content of the relay_domains.db file at the time of failure
with a command like:

postmap -s hash:relay_domains and grep for those missing domain names

Another thing I think you could do help see wheter it was a Postfix problem or
a database problem, is to temporarily switch over to using a btree database
instead of hash.

Is that as easy as changing the hash: to btree: in main.cf, postfix
reload, and postmap relay_domains file?

Yes. Postmap probably defaults to building hash databases, so
you'd have to use: postmap btree:/etc/postfix/relay_domains
for example.
