deliver has the following:

/* After buffer grows larger than this, create a temporary file to /tmp where to read the mail. */ #define MAIL_MAX_MEMORY_BUFFER (1024*128)

...

static struct istream *create_raw_stream(int fd, time_t *mtime_r)

... input = i_stream_create_seekable(input_list, MAIL_MAX_MEMORY_BUFFER, "/tmp/dovecot.deliver.");

On most of my systems, /tmp is relatively small (a few hundred MB, and sometimes on ramdisk), and I like to use /var/tmp for larger temp space.

I just had a problem where I exceeded the space available in /tmp while delivering a (multi recipient) message and had to modify the above line to use an alternative location, and recompile.

Would it be appropriate to make this a configurable option instead?

Thanks.
