I've tried to send this a few times last night and it never made it to
the list. Perhaps I've got something in it that's triggering a filter?
Or perhaps it's too long? (Though I don't think so, there are other
longer posts that have made it to the list.)
So here's another try...
Here's some more info on our system not being able to receive email with
attachments coming from some domains (at least that appears to be the
main symptom at this time.
First, here's a snippet of an error message one of my clients forwarded
to me that his correspondent got when trying to send him email:
> > ----- Transcript of session follows -----
> > 451 4.0.0 putbody: write error: Input/output error
> > 451 4.0.0 I/O error
> > Message could not be delivered for 3 days
> > Message will be deleted from queue
Anyone know what "putbody: write error: Input/output error" might
signify? Google finds it only in one foreign language post referring to
sendmail.
And here (without most of the comments) is our /etc/exim.conf file. It
comes from a DirectAdmin (control panel; see
"
http://www.directadmin.com/") installation, and then an upgrade from
Exim 3 to Exim 4.24; note that some linewrapping may be taking place
here and tabs are most likely converted to spaces by the cut-and-paste
process I used to include the file in this post.
