Hello,
I have been looking to use spamassassin (version 2.20) on our central
mailhubs. I have run it successfully on my linux PC with Exim 4.04. So I
thought I'd move it onto one of the mailhubs - a Sun Solaris 8 box with Exim
3.36.
It all seems to work okay for messages submitted from the mailhub itself
(i.e. I log onto the mailhub and invoke:
exim jhorne@???
('tracy' is the name of the system). The message headers show the
received protocol as 'spam-scanned'. However, if I return to my work PC and
send a message so that it goes via 'tracy', then I get an error returned:
The following address(es) failed:
jhorne@???
Child process of spamcheck transport returned 2 from command:
/usr/local/exim/bin/exim
The following text was generated during the delivery attempt:
------ jhorne@??? ------
An error was detected while processing a file of BSMTP input.
The error message was:
554 Unexpected end of file
The SMTP transaction started in line 0.
The error was detected in line 4.
0 previous messages were successfully processed.
The rest of the batch was abandoned.
554 Unexpected end of file
Transaction started in line 0
Error detected in line 4
==========================================
It then gives a copy of the original message. I installed spamassassin
according to the web site:
http://dman.ddts.net/~dman/config_docs/exim3_spamassassin.html
I am using spamd which was started as root.
The relevant bits of the Exim configure file are:
# Spam Assassin (transport)
spamcheck:
driver = pipe
command = /usr/local/exim/bin/exim -oMr spam-scanned -bS
transport_filter = /usr/local/bin/spamc
bsmtp = all
home_directory = /tmp
current_directory = /tmp
user = exim
group = mail
no_return_path_add
log_output
return_fail_output
prefix =
suffix =
# Spam Assassin (director)
spamcheck_router:
no_expn
no_verify
domains = tracy.csd.plymouth.ac.uk : localhost
local_parts = jhorne
condition = "${if and { {!def:h_X-Spam-Flag:} \
{!eq {$received_protocol}{spam-scanned}}} {1}{0}}"
driver = smartuser
transport = spamcheck
-------------------
I have searched the mailing list archives and can find similar problems when
using the spamcheck.pl script (?), but no real solution. I can find no-one
having this problem when using spamd. I should add that for the trusted
users 'exim' is included, so I can see no reason to have a problem with the
pipe. The error seems to indicate that it is a problem with running the exim
binary, but I have no idea what it is - why does it get an unexpected end of
file? Because local messages work okay I can't run exim with '-d9' since it
won't show any problem (actually I have just done that and I'll check the
output, but it looks okay and no indication of what may cause a problem
remotely).
Very strange. Anyway, as usual these things happen on a Friday afternoon :-)
If anyone has any ideas about this then I'd be grateful.
John.
