I have Postfix currently running as an outbound relay for a Microsoft Exchange system. It's working beautifully, but we are having issues with bounce messages:
It appears bounce messages are trucated to <80 chars (more like 75 according to the tcpdump). This means the error code and message are not handled correctly by Exchange. See below screenshot: https://pbs.twimg.com/media/DBuyDLkXkAEWZ9d.jpg:large I found a reference a possible cause for this in this thread: http://marc.info/?l=postfix-users&m=125273313101833&w=2 This lead me to the source code (and I will stress, I am an admin and not a dev, but I'll have a go) from: /bounce/bounce_notify_util.c /* bounce_print_wrap - print and wrap a line */ static void bounce_print_wrap(VSTREAM *bounce, BOUNCE_INFO *bounce_info, const char *format,...) { va_list ap; #define LENGTH 79 #define INDENT 4 va_start(ap, format); vstring_vsprintf(bounce_info->buf, format, ap); va_end(ap); line_wrap(STR(bounce_info->buf), LENGTH, INDENT, bounce_print, (void *) bounce); } /* bounce_recipient_log - send one bounce log report entry */ Are LENGTH and INDENT variables which can be defined in config? And if not, as I suspect, can I make a feature request that these can be changed with postconf or in a .cf file? Many thanks.
