BSSV Error COSE

Hi, we face error in BSSV side..but seems to be related to SMTP server

bssv:

ERROR CallObject@68cbb2be: COSE#1000 Request timeout: timeout after 90000ms host EONE_SERVER:6017(6023) SocID:50788 PID:18954 BSFN:XPIProcessInboundReceipt user:USER Env:JPD920

COK:

connectToSMTPserver : connect failed
sin_family = AF_INET
sin_port = (printed in host byte order) 25
sin_addr = FTP_IP
Operating system error : <Connection timed out>
Leaving sendMimeMsgOnSMTPImpl with an error return code : <22>

this is related to SMTP settring? blocking or firewall?

BSFN?

or should do I set high BSSV setting time?

any idea..?

thanks in advance
