Hi all, Exim version 4.63 running on Debian Etch (2.6.17-2).
I've been scouring the archives and FAQs and found some similar issues but not exactly matching this one and I am still a little confused so with apologies if I have missed a solution, here goes... We have inconsistent inbound data timeouts from a particular remote host. Both our (exim) server and their (I assume MS Exchange) server report the data timeout and this leads me to believe the problem is a networking connection issue between the two. However as said the problem is inconsistent and does not seem to be message size or sender related as other messages from the same user at the remote host will have no problem getting through. The following message is received by their sender client from the remote server: barracuda.merton.gov.uk #4.0.0 X-Spam-Firewall; host relay.cafamily.org.uk[80.68.87.37] said: 421 ratspen.cafamily.org.uk SMTP incoming data timeout - closing connection. (in reply to end of DATA command) This is the corresponding entry in our mainlog : 2007-03-25 14:41:19 1HVStP-0003TV-H1 SMTP data timeout (message abandoned) on connection from mailout.merton.gov.uk (barracuda.merton.gov.uk) [212.85.21.203] F=<[EMAIL PROTECTED]> At first I had only seen the latter and assumed the remote server was timing out before the end of the DATA command but the message from the remote server says that it at least thinks it has sent the end of the DATA command. The sender is being told by their IT people that the problem is at our end and although I am not convinced it is I am keen to try and resolve it (or at least do a little more to help). In other posts I have seen mention of MTU and tcp_ecm. I imagine the smtp_receive_timeout would make no difference here. Can anyone enlighten me as to why this might be occurring, whether there is anything I can do and what that might be? many thanks -- Ryan Cartwright - IT Manager Contact a Family - http://www.cafamily.org.uk Registered Charity No 284912.
