I'm piping mail from an email address to a php file through sendmail, and everything works fine provided that the email is less than 4kb in size. However, once the mail is larger than 4kb the mails accumulate in the queue until they're flushed out.
Does anyone have any clues on why the size of the email would cause a notable problem? I could understand if it wouldn't process an email of like 100kb.... but > 4kb????
