Hello,
I encounter the following problem with exim.
Upon attempting to deliver mail to paula@??? address. Their SMTP
server immediately closes the connetction after RCPT TO with incorrect
envelope receiver address. As a result, exim process crashed with signal 11.
Here is relevant logfile entry:
2004-06-13 17:41:09 1BX6kh-0006Kp-FI == paula@??? R=dnslookup T=remote_smtp defer (-1): smtp transport process returned non-zero status 0x000b: terminated by signal 11
For debug purposes I issued the following command:

So I believe this is a bug in exim mail server. :)
Any help or comments will be appreciated.
