Re: [Davmail-users] 2 minute delay when sending mail after network change

[Dan C. <jd...@uw...>]

I can reproduce the issue with davmail_5.5.1-3299-1_all.deb available
at https://sourceforge.net/projects/davmail/files/davmail/5.5.1/ ,
so the upgrade to davmail doesn't explain the change.  Not sure what
else to suggest.
