[Evolution] Endless attempts to retrieve or send

[Ralf Mardorf <silver bullet zoho com>]

Hi,

due to a kernel/firefox issue I had to run 'sudo shutdown -r now' by
Ctrl+Alt+F2 (tty2). I did this without closing applications before doing
so. However, Evolution was just opened, but had nothing to do.
Two other MUAs where affected, too and both still work, just Evolution
endlessly tries to retrieve or send. It never stops, doesn't download
or send anything and no messages appear.

POP accounts

$ evolution --version
evolution 3.36.5

Any chance for pointers to fix this, without time consuming debugging?

Regards,
Ralf
