View Full Version : ISP is forcing me to use their smtp relay. Can I avoid this?

So the ISP TMnut is forcing me to route my mail through their open-relay. Not a big issue, aside from the fact that now they could probably read all my mail. The thing is the relay host won't allow me to send attachments that are large (dunno what the minfilesize is, but the smallest I tried is 3.9mb). Is there a way I can circumvent their stupid "anti-spam" measures?

No... and someone correct me if I'm mistaken, but it's at the port level and a part of a voluntary industry-wide compliance scheme involving anti-spam legislation from earlier this decade. Given that it is your ISP and they see all your information anyway it's still "keeping it in the family", as it were.

The industry did that to head off various governments from doing something worse in the name of keeping the world safe from Nigerian princes and their promises of wealth.

My ISP is quasi-government.

So what about this filesize limit thing?

I'm glad they think they are doing something to control spam because it seems to be worse then ever. (joking as I don't see them giving a crap) Open relays are a big contributor. Are you sure about the open part and being open or closed doesn't itself control file size. The best way is for everyone to use the smtp server at their ISP so they can be closed to outside hosts which are the spammers.

BK stop your damned whining. The truth is that no-one wants your fucking emails in the first place.

I don't know which one of your many accounts to send to. Don't want to waste bandwidth by sending to all of them.

How do I use their smtp server in conjunction with my smtp server? They require a username and password and I'm not sure where to put that. I'm using Postfix + Dovecot.

If you have a SMTP server then are you saying they will not pass your server's mail post packets through their network? Your server should just talk to the target of the email server.

Yes. That's why I have to use their relay.

See if there is a way to set up authentication in your server for outbound mail. Seems there would be a way. Guess you have looked into it. There must be a method.
