SMICM error while sending mail using SMTP server

Question

Hi All,
We are not able send mails using SMTP server.
We have made every settings necessary in SCOT, SO16 , SMTP service is activated, default domain is maintained etc
Only things which seems to be wrong is in SMICM trace file.
[Thr 13] *** ERROR => NiBufIConnect: non-buffered connect pending after 5000ms (hdl 29;10.26.24.44:1090) [nibuf.cpp    4608]
[Thr 13] *** WARNING => Connection request from (0/1/0) to host: 10.26.24.44, service: 1090 failed (NIECONN_REFUSED)
[icxxconn_mt.c 2321]
This error is getting repeated in it.
BUt I am not sure why it it trying to hit 10.26.24.44, as we dont have any server by this ip. The ip is only not resolvable from the server.
1 more thing, at OS level, following parameter is maintained in profile :
icm/server_port_1 = PROT=SMTP,PORT=25000,TIMEOUT=180
But in SCOT, under SMTP node PORT is given as 25.
Kindly let me know what going wrong here?
Thanks
