My ISP doesn't allow SMTP

[Guest_imported]

They dont allow the sending of SMTP messages. Is there a way to bypass this?? I don't want to used their SMTP.

You should be able to. It depends on how their blocking foreign servers.

If they have blocked access to foreign SMTP servers by simply stopping stopping port 25 at their firewall, it is possible to set up an external SMTP on a non-standard port. A good number of mail clients can be configured to communicate SMTP on a non-standard port.

If they are doing some kind of packet inspection, there's not much you can do.

ISPs do this for a good reason. It stops some spammer from opening a temporary account, send out 1000000 emails advertising some bad site, closing the account without paying, then leaving the ire of the internet to fall on the ISP.

Why do you want to not use your ISP's server?

I have a question similar to this as well.

Our company uses a mail service (UsaNet) that we go through for our email.

However, we have a server that hosts our website too.
It belongs to us, and resides in our office.
Is there a way to set up SMTP through our own server so that I can use the SMTP from UsaNet?

I ask about deleting UsaNet from the equation because I am writing a program that uses sendmail()(WinIPSTuff class). When I try to send, it looks to our SMTP server( which is UsaNet ) - but gives error 530:authentication required.

So UsaNet is requiring authentication because they require a POP3 logon before sending anything.

If any ideas, please let me know!
Thanks

Do they require POP3 login, or do they require SMTP authentication? ______________________________________________________________________

Hello sleipnir214-
I am not sure actually. It just gives me the error 530: authenication required. I assumed that because I was sending mail, that was handles by the POP3 server, provided by a third party (UsaNeet). Could it be the SMTP server?

Have you contacted your ISP to ask them why you can't send mail? It might be a good place to start.
