question about sending email to ip address postfix

[nephish]

lo there,
i am using postfix as our company email server,
it seems to be working just fine, except when i try to use it to send an email out of the lan to an ip address.

for example 1234@123.456.789.123
will fail
but 1234@somedomain.com
will work.

is there something i can do about this ?

thanks

Sure - wrap the IP address in [ ] e.g. 1234@[123.456.789.123] then Postfix won't perform an MX lookup on the 'domain'.
