Are you using SSL connections? If so, this is the well-known Microsoft SSPI size bug which Microsoft acknowledged month ago (see MSKB article 300562), but *still* has not distributed a hotfix. SSPI is the facility in Microsoft operating systems that implements SSL. Contrary to what the MSKB article says, this bug is *NOT* a "Pine problem"; the same SSPI bug also provably breaks Exchange server. Basically, this bug means that you can't send full-sized SSL payloads to any software which uses SSPI. Newer versions of Pine and UW imapd try to work around the problem by limiting their SSL payload sizes. Software using SSPI is still quite capable of *sending* full-sized SSL payloads. The problem occurs in *receiving* full-sized SSL payloads; SSPI does not tell the application to allocate enough buffer space.
