My reading of the entry.  Subject to random incorrectness :-)

You're logging accepts on your firewall, (ACCEPT) which might be a bit rash,
as you'll fill your logs pretty quickly.

The box 132.181.30.7 is trying to send your box (10.0.0.5 I assume)
something to the smtp port as a reply (tcp, port 25) to an established
session from that port (no SYN flag).

Dunno what else I can say.  If you are not expecting connections to that box
for mail delivery someone might be playing with that box.

I assume you're on a dial-up or ADSL and this log is from a masq box between
you and the net?

Cheers,  Chris Hellyar.

Can anyone throw light on why the following appears in the messages file on
my firewall:

Apr 21 06:15:42 gateway kernel: Packet log: input ACCEPT eth0 PROTO=6
132.181.30.7:2844 10.0.0.5:25 L=75 S=0x00 I=23583 F=0x4000 T=53 (#13)

132.181.30.7 resolves to regyva.canterbury.ac.nz
