That's broken... Something between Perl and your log is mangling and
truncating the error message. Maybe the Postfix 'pipe' plumbing? That's a
secondary issue though, as it is easy to run SA by itself to. find the
problem.

Try this:

   spamassassin -D all --lint

That should give you a large amount of debug output including the
original error message with a file &  line reference.


These are the lines in master.cf that points to the pipe for filter:

[...]



That solved the problem. It was a single ruleset, and I removed it.

I thought I only had default rulesets, but I guess I added a few extra ones 
over the years.


Thanks for your help. Errors bug me to no end, as you've probably figured 
out by now.

I did the following searches trying to locate this issue:

# grep -ro "\[,.\]" /usr/local/lib/perl5/site_perl/*


The warning message only applies to '{' NOT '[' and NOT '('

[...]


# grep -ro "{,.}" /usr/local/lib/perl5/site_perl/*


Try "{,.*}" instead. Also, don't use the 'o' option to grep. It 
eliminates useful context, specifically whether the pattern is inside a 
regex.

The same searches run on SA rules found one possible issue:

# grep -ro "\[,.\]" /usr/local/etc/mail/spamassassin/*
/usr/local/etc/mail/spamassassin/70_sare_specific.cf:[,s


As I said in my prior message: remove that file and any others with 
'sare' in their name. They are dangerously obsolete.


Also check /var/db/spamassassin, which is where anything maintained by 
sa-update will be.


I say possible because in my researching this issue I've seen both 
curly braces only and also both curly braces and square braces, so I'm 
not completely certain which (or if both) are a problem.


It's always helpful to look at actual documentation, rather than trust 
research of secondary sources...


Try 'perldoc perldeprecation' for the definitive truth of deprecation 
warnings.


At any rate, I don't see any dependency on Text::Unicode, although I 
wouldn't be surprised if it's used by SA.


It absolutely is not, because Text::Unicode does not exist. :)

SA also does not use Text::Unidecode, which is a last-resort tool for 
special cases where Unicode characters absolutely must be translated to 
a reasonable US-ASCII representation.

That is NOT part of the default ruleset. For a few years there was a 
3rd-party collection of rules files known as SARE which was distributed 
independently of the SpamAssassin project. It was last updated well over 
a decade ago. No one should be using those rules with a modern SA to 
catch modern spam. They are neither safe nor effective. Remove any rules

It would be a wise choice to update ALL of your Perl modules to the

So, I would assume it would be one of these modules?

   re2c>=.12.0:devel/re2c


Those or any of the modules upon which they depend, recursively.

There are also Perl modules that will NOT appear as hard dependencies of 
SA anywhere because they are optional or only required for particular 
features. When running the build of SA, these will be looked for and 
noted by Makefile.PL.


It is also possible (even likely) that this particular error is the 
result of problematic syntax in a SpamAssassin rules file, because many 
rules include regexes.

This is a new warning in Perl 5.26. The use of curly-brace regex

It's not unusual for a mail client to "transform" error text, for
example, to display a message in the local language. The 5.1.3
status code is preserved.

If that's postfix, it may be using a different delivery path. Or

Current behavior is no indication of historical behavior, unless you
have repeatable and consistent results.

"A" always answers "foo"
"B" always answers "bar"
is something to investigate. Otherwise, chalk it up to a temporary
external error.

With vanilla syslog daemons, splitting the files might be easier
by setting "-o syslog_facility=local1" or something similar in
master.cf, and having a rule "local1.* /path/to/file" in
syslog.conf.

You MAY have to create the new logfile by hand, and you WILL have
to update the logfile rotation procedure.

you MUST NOT stop bounces

you have to look why they are happening and solve
the root-cause which is maybe you do not reject
messages to non-existent rcpt directly

if you accept a message and it can not be finally
delivered the server sends a NDR, if you reject
the message the sending machine is responsible
for the NDR - so maybe you are a backscatter
