Judging from his presence on the Exim-related mailing lists he is probably 
using the Exim MTA and its ACL facilities.

I am having difficulties getting AUTH to work for remote connections. I have had it working in the past, but don't normally use my server for sending e-mail because it has a dynamic IP. Yesterday I found that it doesn't seem to be working at all. I have tried with Thunderbird and Opera to send e-mail, both say something the server is not accepting SMTP connections or is not set up properly.

Any chance that your ISP might be blocking incoming port 25? Does
submission on port 587 have the same problem?

The problem was along these lines. Port 25 seems to be blocked for outgoing on the network I was testing the e-mail client. I added listening on port 587 for situations like that and everything is working now; or rather it was always working and I just now realised it. Thanks for pointing out the most obvious reason. It could have taken weeks for my brain to turn on.

I also found that when using telnet remotely, the welcome banner was very slow to come up ~60s. I set rfc1413_query_timeout = 0s to get

around that.

If that didn't help, you might be experiencing DNS issues. If it
helped, I have no idea because rfc1413 timeout was always shorter than
30 seconds.

Thanks again.

Yes, you're right. I reset to 30s and from some hosts it takes about 35s and from others about 3s. I must have made a mistake when I measured 60s. I have set the timeout to 5s, which I think is the default for exim 4.6 (I have 4.5).
