hi all please i need help i got an Error while trying to use public Burp Collaborator Serve every thing is working fine but is seems like there is a problem in SMTP connection burp tell me this message : An SMTP connection to the capture server at bapieum1pa4mezlslrx70706ixoa2tmbqef.burpcollaborator.net port 25 could not be opened. Communication using other protocols did work; possibly a firewall is preventing this connection. so how to fix this issue ?
