If a regular member's options include "nodupes" and the member's
address is in a To: or Cc: header of the post, Mailman will not send
the post to that member. This does not seem to come into play here as
the number of regular members is 58 and the number of smtp recipients
is also 58, thus we don't have to account for any "missing"
recipients. If we did have to account for missing recipients, we would
have to see if any regular members were in To: or Cc: headers before
concluding there was a problem. This is what I meant by "minus the
number of "avoided duplicates"".

In your case, it is simpler. There are 58 regular members, all of whom
are receiving mail and mailman claims to have sent the post to 58
recipients. So far, so good.

It seems to agree with Mailman that there were the expected 58
recipients, thus the issue seems to be on the outbound side of Postfix.

You could look at Mailman's bounce log to see if anything bounced for
this member, but presumably you would have already seen it in the
Postfix log if it had.

Perhaps the member has a filter at his end that treats the message
differently if it is From: him. Perhaps some kind of spam rule that
assumes a message From: him that is not explicitly addressed (To: or
Cc:) to him is SPAM.
