Title: Port 25 spontaneously blocks?
Post by: Mike Schultz on July 16, 2001, 11:37:05 PM
I am running qmail here and it has been working fine for at least a week.  When I arrived today, however, no incoming mail was being received and a look at the logs revealed these:

Jul 16 14:12:45 e-smith kernel: Packet log: denylog DENY ppp0 PROTO=6 yyy.yyy.y.
yyy:55430 xxx.xxx.xx.xxx:25 L=48 S=0x00 I=62259 F=0x4000 T=248 SYN (#1)

from the various servers trying to deliver the messages.  I restarted the firewall rules by issuing masq restart, which cleared the problem.

I am still running 4.1.1.  Any ideas as to what caused this?
TIA
