We have resolved our external tests problem by installing the djbdns caching dns server (http://cr.yp.to/djbdns.html) on the amavisd/spamassassin relay server. Prior to installation the log was showing TIMING reports of ranging from 10000 to 50000 ms, with the average being about 18000 ms. If we enabled any external test this was the result. Now all messages are processing with TIMING results of 300 to 2600 ms with the average being about 1200 ms. Since making the change our system has not fallen behind or been under any significant strain at all.
The reason: apparently the dns load from the relay server was sufficient to drive our primary dns server's cache into some form of corruption. It would resolve local sites fine but not external sites until reset. As a result the relay server was then failing over to the secondary dns server to complete the external queries. Since the primary server was partially responding it seemed to always get first crack but failed. The relay server could put the dns server into this state in about 18 hours, but I had never seen this before under normal usage. Looks like I need to work on the dns servers...
