I only told it to connect to [mail.gmx.es] using port 465, I did not tell it to change anything else.
Then the thing demanded I do:

which I did, then it complained about a library version problem:
As Andrei has explained, you have changed the global settings for the postfix smtp client. These will also be applied internally, e.g. for amavisd.
Why on earth are the changes needed for the external ISP GMX.ES affecting the internal amavis handling?
Well, you changed it globally, so they affect everything.
Otherwise, how on earth do I configure postfix to send to gmx.es using port 465 properly without affecting the rest? Surely people on this continent using the daft Bell network must do something?
Restricting port 25 and asking people to use port 587 for mail submission has been standard ISP practice for years and years.
Not in Spain. They don't block anything. Freedom, you know? ;-p
Do they not block port 25 to other than their own networks? That is what usually happens - outbound port 25 to other networks in blocked, and the standard support answer is 'use port 587'.
I tried submission first, and it failed.
The automatic configuration with Thunderbird uses 465, and Andrei said submission is not 465.
Except on Telefonica, they do not allow submission, use 25 instead.
If they don't do any hosting and only service their own customers on their own networks, that is a safe setup. -- Per Jessen, Zürich (25.0°C) http://www.hostsuisse.com/ - virtual servers, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
