Travel SMTP works in EVERY situation!
Travel SMTP always accepts your connection
Travel SMTP will always accept your emails, no matter where you are, from any location, any network, any country, any device and any email software.
Firewall-Proof setup
Travel SMTP has a very unique Firewall-proof feature: in addition to listening on default smtp ports, it also listens
on port 80 and 443. These ports are normally used for standard internet traffic, like regular traffic to websites.
When you use this setup, no firewall will stop you from sending email: if you can visit websites, you can send email!
This is extremely useful in
hotels,
campsites, WiFi hotspots and in some areas like China, or any other network where only regular internet traffic
is allowed to pass through.
