The SA rules are not signatures as such. The core rules tend to be fairly generic, so missing an update here and there isn't that much of a problem - it's not like missing an antivirus update. If you have a problem with reliability there nothing to stop you running sa-update several times a night. If the rules are up-to-date sa-update is just a single DNS lookup. > Here below there are two manual attempts (wgets): > One with a bad mirror (1) and one with a good one (2): > > 1) > wget http://sa-update.spamassassin.org/1853564.tar.gz ... > HTTP request sent, awaiting response... *503 Service Unavailable* > 2019-02-15 12:47:51 *ERROR 503*: Service Unavailable This worked for me when I just tried it, and I don't have any recent sa-update failures. > > So I ask you if it's possible to intervene on the mirror's list with > some option so that to exclude the bad mirrors. In the short term you can edit unwanted mirrors out of the MIRRORED.BY file. It will get replaced after a week (if you don't touch it). It's worth trying just to see what happens.
