suddenly unable to send email

hosting provider says it has to do with ISP--does this sound right to you?

I've been a hosting reseller for almost a year now. In the last 10 days I've been getting reports from clients that they are unable to send email through the domains I host. I also started to experience the same problem.

The error message I get is either simply "Unable to connect to host" or "The connection to the server has failed. Account: 'mail.mydomain.com', Server: 'mail.mydomain.com', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 10061, Error Number: 0x800CCC0E"

My hosting provider told me to change the outgoing mail port on my email client to port 26. The problem has diminished, but I will still get this error on occassion.

When I asked for an explanation of what was going on, the hosting provider said that my customers' ISP was no longer allowing mail to go out through port 25. This seems odd to me as the clients who complained are on different ISPs so for them to suddenly shut down this port within days of each other doesn't seem likely. Also there is no problem sending hotmail via this port.

What do you think? Is this a reasonable explanation, or should I be looking for another hosting provider?

Yep. Happening all over the place with ISP's. See encyclo post #9. [webmasterworld.com...]

I have SBC and had to set up all my domains to send and recieve through my single SBC account instead of my host for each domain. It works just fine set up that way, and helps to stop spam...

I don't know if this applies or not, but let me give my experience.

My site USED to be hosted at some outfit that rhymes with Jizzland.
People used to email in via webmaster@mysite.net,
and that would be redirected to my personal dial-up ISP.
All of that dried up so I sent myself a test message.
Obviously, that didn't get thru either or I wouldn't be writing this.

I emailed my dial-up ISP, gave them DNS numbers etc.
and they said (in effect) HAHAHAHAHAHAAH!

It turns out my old host was a major email spam pipeline.
Spamcop and others blacklisted them, and there were
other very seamy allegations.

I changed host ISPs and the problem vanished as if my magic.
It took about a month to tie up all the loose ends,
but it was well worth it. I'm actually paying less
now with an honest host. -Larry

Thanks Jon_King. At least now I know that my hosting provider isn't giving me the 'run around' :)
