After the error message is logged, the code in imap_fetch_send() invokes 
this:

mail_set_cache_corrupted(ctx->mail, ctx->cur_size_field);

What uses that? Is that supposed to ultimately prevent the retry from using 
the cache file? It seems like that mechanism isn't working, as the client 
was getting into a loop.
