try the following:
no access-list smtp_in extended permit tcp any host MailServer2 eq smtp
access-list smtp_in extended permit tcp any host eq smtp
Because currently your ACL is allowing access to MailServer2 (which I suppose is the

also I see the "access-group smtp in interface outside"
shouldn't that be:
access-group smtp_in in interface outside
CHeck to make sure you still have a rule allowing SMTP inbound. Also check for your static NAT statement (if you were using one). If you post a sanitized config I can take a look at it.

This is access list and NAT config and my mail server IP address is

access-list 101 extended permit ip 255.2
access-list outside_access_in extended deny ip any any
access-list 80 extended permit ip any
access-list smtp extended permit tcp any host eq smtp
access-list smtp_in extended permit tcp any host MailServer2 eq smtp

global (outside) 1 interface
nat (inside) 0 access-list 101
nat (inside) 1
static (inside,outside) tcp smtp MailServer2 smtp netmask 255.255
access-group smtp in interface outside

Is esmtp inspection disabled? If not try disabling it.

Yet having the problem, then post the config.

Now problem is solved one of the my freind suggest me solution

Could you please issue the following commands:
  no static (inside,outside) tcp <public_ip> smtp MailServer2 smtp
  static (inside,outside) tcp interface smtp MailServer2 smtp netmask

If you're using the interface IP address on static NAT entry, you're
 required to use the "interface" keyword instead of the IP address (as you
 can see in the command reference:
"Note You must use the interface keyword instead of specifying the
 actual IP address when you want to include the IP address of an interface
 in a static PAT entry."
:-) that is the reason I asked to post the config. Not just there, you need to make changes to the acl as well;

Your acl should read as below;

access-list smtp_in extended permit tcp any host interface outside eq smtp
