[Mimedefang] mail server not issueing helo ro similar

[David Gwynne]

I've seen this caused by a perl script using Net::SMTP. It issues a HELO
line that sendmail didn't like so the connection was closed. That entry
showed up in my maillog.

The weird thing is I have another 4 boxes using the same module and they
don't have this issue. I worked around it in this situation by using this
"define(`confALLOW_BOGUS_HELO', `True')" in my sendmail config. However, I'm
sure there is a better solution. I just don't know what it is.
