SpamAssassin Invalid cross-device link

[sandeepb1]

When enabling the spam_filter option in config and installing spamassassin I am presented with an error whenever MailWay scans an incoming email.

This looks like Spam Assassin not liking the fact it has to scan a file in the /run directory, when re-running the command to the original /tmp location everything works without issue.
