I have, very rarely, seen an issue where the callout target delayed a response for longer than the original sender's smtp timeout. Not in the past few years, though. However, that would probably mean that a site would, theoretically, have trouble sending mail to itself. Either its tarpitting policy is unfeasibly harsh, or its persistence in the SMTP phase is very optimistically small. -- Ian Eiloart Postmaster, University of Sussex +44 (0) 1273 87-3148 -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
