Over the weekend I changed by broadband from the Adventure Plan to Big Time. I plan to do some pretty huge backups to the cloud over the next couple of months so the additional data will come in really handy.

I use an external mail server however, and since the change over I am no longer able to connect to it on port 25. I have the opt-out on my account, but I get a "Socket Error #10600" when I try and connect to the SMTP server.

I spoke to Telecom, and the rep also spoke to his supervisor, who both said it should work fine and they will have someome take a look. I have however also heard from one other person who experienced the same thing when they changed to Big Time, that Telecom told him that Port 25 opt out is not available on Big Time.

I can't see any info on this anywhere on the Telecom website however.

Has anyone else noticed this on Big Time, or got the Port 25 Opt Out working?

I had this very same problem, the complex technical response team initially said it should work fine then said that "port 25 opt out is currently unavailable on the Big Time Plan"

So unfortunately it's a no go at this stage

Did they say why? Is it a technical thing or a policy thing?

No they didn't say why but I would imagine it's because of the different pools of IP addresses they alocate to big time eg:

Regular broadband users have one pool of IP addresses, regular broadband with port 25 opt out have another pool and big time with no port 25 opt out have another etc.

I would imagine that's it's perfectly possible but at this stage not in their plans.

Most 3rd party email service providers also work on port 2525 these days because of the widespread ISP port 25 blocking.  Is your server also accepting connections on an alternative port?

No unfortunately it's port 25 only and host wont open any other ports for security reasons.

What about SMTPS (SMTP over SSL) as that works on TCP port 465..

2525 isn't a standard port.  Most decent mail servers these days also support 587 out of box, which is the mail submission port.

Of course, adamj could always use the Xtra outgoing mailservers if these alternate aren't options.

I don't want to use the Xtra mail servers - I've had no end of trouble getting this to work well in the past.

Oh yeah I forgot about 587, I've seen quite a few hosts work on 2525 even though it's not a standard.

If you can't use 465 and 587 and don't want to use send.xtra.co.nz then you'll have to use a tunnel/vpn/proxy to another host without port 25 blocking I guess.
