Another mailclient, Claws-Mail, is reported to also be affected by the POP3 TLS handshake failure for Yahoo mail managed email (AT&T, AOL, BellSouth, Verizon) on Ubuntu 18.04 base.
This may be an issue with some system libraries used by both Evolution and Claws-Mail and maybe whatever security tightening Yahoo mail did recently. A user of Evolution on Ubuntu 18.04 base reported to get Evolution to work again after installing these packages from Ubuntu 20.04: libffi7 libgnutls30 libhogweed5 libnettle7 libp11-kit0 Not narrowed down yet but above may hold clue as to which package in Ubuntu 18.04 base is the cause. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876286 Title: Evolution reports "Error performing TLS handshake: Internal error in memory allocation."
