cannot connect to SMTP server connect error 10060
The so-called 'port 25 block' is an anti-spamming measure that
has been adopted by most providers of Internet connectivity.
Basically it means you will not be allowed to use port 25 SMTP
unless that server is on the same network as the one providing
your Internet connection at that moment. This policy causes a
hardship for travelers. There are some workarounds:
1. Use webmail.
2. Use a port other than 25 for SMTP, if your mail provider
has a provision for that. Typical alternate ports are 465 and 587.
3. Get a free Gmail account, configure it for POP access, and
use it for your sending chores.
