well.
beyond the hellish problem with tde refusing to believe it when i tell it to accept a certificate forever, which makes interval mail checking impossible, there is the "unable to complete LIST operation" error, which pops up now and again on a daily basis. i've read archives which suppose there is some malformed spam in the inbox causing this. but there isn't. and in due course it tends to go away without any intervention on my part.
are there in existence workarounds for these? the patch for the certificate issue i have not been able to make compile -- surely there's a binary for the file involved, somewhere. the LIST issue i cannot find a solution for at all. both are after the upgrade to the current distribution for ubuntu 12.04.
