Re: Odd ipfilter/postfix interaction

[David Bogen]

Since I had trouble finding the source of the problem, I decided to try 
ipfilter 4.1.6 on the off chance that some unrelated change had solved 
my problem.

No dice.  Messages with even small attachments were still blocked.
Then, without changing anything else, I re-installed 3.4.35.
Messages started flowing through the system once again.
So, whatever is causing undesirable interference with postfix seems to 
be lurking in the 4.1.x branch of ipfilter, and not the 3.4.x branch.
