POP3 TOP instead of RETR? [message #2075] Mon, 03 January 2005 07:36

Is there any way to get NoSpamToday! Workstation to process mail for a client that fetches mail using the TOP command (to get only a specified number of lines) instead of the usual RETR?

I have it working fine for normal clients like Eudora, but I'd like to use it as a proxy for Mailwasher Pro. Mailwasher issues only TOP commands unless it encounters a TOP error, in which case it will issue a RETR, but logging shows that NoSpamToday! passes TOP commands though without filtering or returning an error.

I realize that TOP is optional for RFC compliance and that there are risks in modifying headers with TOP, but other proxies (e.g., POPfile) have workarounds for TOP, and I'm hoping that NoSpamToday! does as well.

For best classification results, SpamAssassin has to analyze the complete message
body, so I don't think it makes sense to support the TOP command as a trigger to
start the spam check.
