Author: Simon Barr Date: To: Exim Users Subject: [Exim] Exim and Spamassassin pipe problem
Hi all,
Apologies for the long post.
Exim 3.30
Spamassassin 2.20
I hope someone may have an idea whats going wrong here. I've
searched the list archive and can find only one other person
who had a problem similar to this, and his fix won't work in
this case I feel.
Having given up on Razor as ineffective I thought I'd try out
Spamassassin to see if it is any better, and it is!
I have got SA up and running and it is currently catching
much more spam than Razor did, but I have an intermitent
problem. Occasionally a mail fails when passing through the
following transport.
spamcheck:
driver = pipe
command = /usr/exim/bin/exim -oMr spam-scanned -bS -d9
transport_filter = /usr/bin/spamc
bsmtp = all
home_directory = "/tmp"
current_directory = "/tmp"
user = mail
group = mail
return_path_add = false
log_output = true
return_fail_output = true
prefix =
suffix =
# Adding header, we will check for this header in the system filter. If
# the header is set we will not copy the mail to archive, this stops
# duplicate copies of mails. Otherwise the mail would be copied again on
# its return from being scanned by spamc.
headers_add = "X-Spam-Checked: True"
path = /usr/bin:/bin:/usr/lib
I've added the -d9 to the command to help in tracking down the problem.
When a mail fails I get an entry in the mainlog thus:

The returned message includes the following debug info which doesn't
mean an awfull lot to me. I can see that the is an EOF that is causing
the error but have no idea what may be causing it..

An error was detected while processing a file of BSMTP input.
The error message was:

The SMTP transaction started in line 0.
The error was detected in line 3.
0 previous messages were successfully processed.
The rest of the batch was abandoned.

The mail server processes around 150-200 mails a day and I get a
problem with maybe 8-10 of them.
Could this be an Exim problem or a Spamassassin problem? Any ideas
gratefully received. If I can't fix this I may have to just put up
with spam and I don't really want that :-(
