Hello Sergey, > The following patch fixes the bug
That sounds great! Do I assume it right there's no sloppiness/not-standardness in Migadu IMAP server configuration (related to the fixes)? To test the fix, I tried to install mailutils from the source, but after git clone https://git.savannah.gnu.org/git/mailutils.git I couldn't find nor 'configure' nor INSTALL file (both are gitignored) nor installation instructions in the online documentation/manual. [I've dug up on the mailing list the instructions are in README-alpha, but INSTALL is still mentioned in the README file.] At the same time, I do see 'configure' file can be present, as it's used by Homebrew https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/mailutils.rb What am I missing here? Thanks, YE
