Thank you for all your precious advices and considerations, expecially for privacy-releaded concerns. Indeed, I'm very well aware of this aspects, but perhaps you're missing my point: the mailbox will be used *only* for mailing lists, which content is (usually) of public domain, on the web. So privacy is not a strict requirement in this *specific* use case. I won't feel too bad if my $MAIL_PROVIDER mines data from my mails since they're not private ones, but i won't feel ok if the mailbox don't work well technically. As I stated before, I want:
– no ramdom spam filtering (at least the chance to disable the spam filter, which it seems Y don't let me to). – full (no restrictions on the amount of data transferred) and stable imap access. Since I'm not reading (particular) complaints about Gmx, I think I'm going to give it a try, subscribing to MLs I'm already sub on this Y account. Just to see how it behaves, and then I'll decide whether making the "switch" or not. Thank everyone again! -- fp
