Exim took the port number 465 from somewhere in its config. 465 is the TLS-on-connect port. In some other part of config you specified 587, but Exim nevertheless tries TLS-on-connect. Search for "465", post relevant parts of your config. Better entire config. -- ## 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/
