I use the default sendmail for sending email,
which could conceivably be the cause of the problem.
That _may_ be the problem. Many mail servers black-list port 25
connections from ISP network addresses. I long ago changed my
configuration to use my ISP's mail server designated as its relay for
customer use. If I send mail directly from my machine to the
destination, it often is filtered because it comes from the
black-listed network.
I believe this is an attempt to cut down on zombie-sourced spam.
