If I understand well, not down *this connection*. The ETRN just triggers a queue run for the domain in question. Asking for all the security considerations… (I think, actually Exim allows you to specify a custom command to run on ETRN, but even with the custom command it's not possible to use the connection established from the client side.) But I may be wrong. -- Heiko :: dresden : linux : SCHLITTERMAN.de GPG Key 48D0359B : 3061 CFBF 2D88 F034 E8D2 7E92 EE4E AC98 48D0 359B
