Unescaped left brace in regex is deprecated sa-learn error

[km9]

I've been getting an error on running the spamassassin sa-learn script on emails to learn spam:

Unescaped left brace in regex is deprecated here (and will be fatal in Perl 5.30), passed through in regex; marked by <-- HERE in m/(?is)spam title here claim.{1,10}your.gbp|won.you.{ <-- HERE 1,10]gbp)/ at /usr/local/cpanel/3rdparty/perl/528/lib/perl5/cpanel_lib/Mail/SpamAssassin/Conf/Parser.pm line 1403.

(Note the curly bracket followed by a square bracket syntax error): "won.you.{1,10]gbp"

I don't have WHM access on this server, but I've checked the /etc/mail/spamassassin/KAM.cf file, and the syntax there is also incorrect:

find / -iname kam.cf

/etc/mail/spamassassin/KAM.cf

grep "1,10]gbp" /etc/mail/spamassassin/KAM.cf

body        __KAM_LOTTO5    /spam title here claim.{1,10}your.gbp|won.you.{1,10]gbp)/is

I've spoken with the support team for this particular server, but they seem nonplussed by this problem. How do I explain how to update this KAM.cf to a version without this syntax error?

Thanks.

Edit: Yes, I do mean "/etc/mail/spamassassin/KAM.cf" (not /usr/local/cpanel/etc/mail/spamassassin/KAM.cf)

Actually, I think that this is the key: I do mean "/etc/mail/spamassassin/KAM.cf" (not /usr/local/cpanel/etc/mail/spamassassin/KAM.cf)

I did 'ls -la /etc/mail/spamassassin' and got this:

Note there's only 1 file that is a link, and the KAM.cf dates from 2015. I believe every entry except init.pre, kill-spamd.sh, local.cf, sa-update-keys and the four *.pre files should be linked to /usr/local/cpanel/etc/mail/spamassassin/...

So now the question is: how can this directory be corrected? I thought it might be checked during the cpanel update?

 

[km9]

Lots of views, but no suggestions as to how this directory became corrupted, or how to put it right?

(Thanks to the moderators for changing the title of this thread, I actually thought that the original subject referencing KAM.cf directly was more apt though, in this case)

Hi @km9

There should definitely be symlinks there - and there should be updated information. The cPanel update would normally encompass this. Can you show me the output of the following

cat /etc/cpanelsync.exclude

cat /etc/cpupdate.conf

 

[km9]

Hi, thanks for the interest, but I don't have root access to this machine, and I persuaded the support team to reinstate the links manually:

ln -sf /usr/local/cpanel/etc/mail/spamassassin/BAYES_POISON_DEFENSE.cf /etc/mail/spamassassin/
ln -sf /usr/local/cpanel/etc/mail/spamassassin/CPANEL.cf /etc/mail/spamassassin/
ln -sf /usr/local/cpanel/etc/mail/spamassassin/KAM.cf /etc/mail/spamassassin/
ln -sf /usr/local/cpanel/etc/mail/spamassassin/P0f.cf /etc/mail/spamassassin/

Which solved the problem.

Neither of those files exist though:

(cat: /etc/cpanelsync.exclude: No such file or directory,
cat: /etc/cpanelsync.exclude: No such file or directory)
