I'll try a rather thorough relaytester on it - http://www.monkeys.com/mrt/ > relay, it is not so. It accepts third party mails, but doesn't > deliver them. Instead drops them. That's supposed to be exchange's default behavior, but older versions can be massaged into relaying for one combo or another (using weirdly formated but legal smtp constructs). This is in addition to the one or more holes that stupid cisco pix mailguard you have in front of your server opens you up to if misconfigured. The pix, even when properly configured, makes a absolutely lousy mail proxy... breaks ESMTP, holds up tons of mail courtesy extra stupid packet filtering rules and MTU path discovery issues (causing duplicates etc) ... Cure = # no fixup protocol smtp 25 on the pix. Then put sendmail or something similar there. -srs -- Suresh Ramasubramanian <----> mallet <at> efn dot org EMail Sturmbannfuhrer, Lower Middle Class Unix Sysadmin [Linux One Stanza Tip] From : <[EMAIL PROTECTED]> LOST #220 -**< Sub : Unix to mac conversion (#1) >**- If you have vim editor installed, the following will do a mac to Unix (text file) conversion: #!/bin/sh # Save u2m, chmod +x u2m vim -c ":set ff=mac" -c ":wq" $1 # Usage: u2m filename.txt ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ linux-india-help mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/linux-india-help
