Message size limit for sa-learn

[Wolfgang Zeikat]

We have set -s for spamc to 350k - and we can use spamassassin -t on 
messages of that size, but we can not sa-learn them, sa-learn -D -t puts 
out:

[17460] info: archive-iterator: skipping large message
Learned tokens from 0 message(s) (0 message(s) examined)
Can we pass the 350k limit to sa-learn somehow?

Regards,
