Hello,
I 've got some problem with my Mail Server since I've migrated to an ASA5510.
Actually the server is in a DMZ with a private Ip ( 10.x.x.2) and it is translated to a Public IP ( 194.x.x.65).
I use these configuration :
static (DMZ,LAN) 194.x.x.65 10.x.x.2 netmask 255.255.255.255
static (DMZ,LAN) 194.x.x.66 10.x.x.3 netmask 255.255.255.255
static (DMZ,WAN) 194.x.x.65 10.x.x.2 netmask 255.255.255.255
static (DMZ,WAN) 194.x.x.66 10.x.x.3 netmask 255.255.255.255
static (LAN,DMZ) 192.168.0.0 192.168.0.0 netmask 255.255.248.0
Some Users received in there mailbox a system administor error message :
Object : Impossible to deliver : test
Your message could not be deliver to one or more of its recipients: 421 SMTP connection went away!
When they try to re sent it some times later, message is sent whithout problem.
Any Ideas about it ?
