Hi, Since no-one else replied...

If you're defering lots of connections, I'd have thought the delaying of much normal mail from proper MTAs that *do* retry would be more noticeable to users than the rare loss of something that doesn't retry. -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
