Hi,

(Possibly in relation to 
http://lists.swinog.ch/public/swinog/2021-March/007457.html, but in this case 
not even a TCP ACK...)

It seems smtp.bluewin.ch (25 and 465 tested) is unreachable from all places I 
checked (Init7, Quickline, BIT.nl).

Is that service normally open for Bluewin customers to connect to 
smtp.bluewin.ch?

As apparently Swisscom is sending out mails to providers that their customers 
are complaining that their customers on non-swisscom/bluewin cannot use their 
SMTP service.....


But telnet does not even answer.... (no TCP ACK at all, no ICMP, nada nothing), 
thus looks like it is firewalled away.

Greets,
 Jeroen
