Email rejected as spam or SMTP server blacklisted?
1. Basic authentication used by most normal SMTP servers
leaves them open to abuse by spammers and scammers - this can
cause them to be blacklisted meaning your mail may not be
delivered!
2. We authenticate each login, validate email addresses used
to send mail, enforce quotas, virus scan mail sent and use other
methods to detect / stop potential abuse making our service much
more secure and reliable.
3. If you try to send mail from a dialup / broadband
connection many ISP's block port 25 (used for sending mail) and
even if they do not many other ISP's will reject mail from you.
Relaying your email through AuthSMTP can solve this!
