Letters are not delivered!!! again!
Before the changes introduced by yahoo, we could check if yahoogroups are sending letters, now, unfortunately not! Letters from the forum_psch group do not reach the addresses, e.g. in the domain @ op.pl or @poczta.onet.pl Please correct the mechanism of delivering letters. We don't even know if the person sent a letter. There is no log with a header that could be used for verification. There are no letters sent on June 19 and the following days.
