Emails are not sending (2.7)

[hostonnet]

Many web servers do not allow remote smtp connections as it is used by spamers to send bulk mail, it is difficult to find who send spam if such smtp mailing is allowed as there is no customer headers are added to outgoing mails. Cpanel servers have option to disable remote smtp connections.

I have checked on several blacklists, and my servers were not listed.

I changed the data as you said, and now I receive emails without problems with SMTP.

Thank you!!!!

Nice to see you got it working. Large mail services like yahoo, hotmail, aol etc.. got their own black list. Mostly checking mail server log will provide some information.
