From another server, where I prefer to keep the mail, I use
fetchmailto grab the mail via IMAP, and remove it from that other server if I've successfully retrieved it.
For the most part, this works excellently.
But lately, I've been encountering a situation where certain emails (usually ones with many lines of quoted messages; replies-to-replies-to-replies...) are rejected as "exceeding maximum size" (despite being only medium-sized) ... and deleted! from the server where I'd already received them and they were fine!
SMTP/ESMTP ERROR HANDLING Besides the spam-blocking described above, fetchmail takes special actions on the following SMTP/ESMTP error responses 452 (insufficient system storage) Leave the message in the server mailbox for later retrieval. 552 (message exceeds fixed maximum message size) Delete the message from the server. Send bounce-mail to the originator.
What? How is either of those things the right thing for
fetchmailto do in this situation?
