This is somewhat redundant now, but the information is a little more
precise than previoius replies.

At a guess "TOSA" = "terms of service agreement" and "BL" = "block
list". That's supported by the SMTP status 554 (denied for
administrative reasons) and the link below. But http://mxtoolbox.com/
says you're not on any of the 95 RBLs it checks. So it must be
internal. Google is my friend, and told me to look at
So it looks like t-online has taken a severe dislike to you ("BL"
apparently means they've decided you're a long-term bad actor). If you
are in the fortunate position I am, you tell the user that t-online
is f++ked and they should get a new address. If you're not, write to
tosa at rx.t-online.de and beg to be reinstated in their good graces.
 You can generally ignore my footnotes. It's my way of denoting a
a-political rant. :-)
 My employer, the Japanese Ministry of Education, prohibited use
of Yahoo addresses for academic business after the Yahoo!/AOL April
Fool's Joke of 2014. But strictly speaking, it turns out that it's
the Ministry that's f++ked because they can't tell the difference
between yahoo.co.jp, which causes no DMARC problem (they don't have a
p=reject policy), and yahoo.com, which has both DMARC *and* privacy
issues out the wazoo. But I ignore that, since I hate the garbage
that Yahoo's wannabe MUA emits. ;-)
