Expected behavior

K9 should be able to handle large lists of recipient in TO list. I e.g. wanted to send an email to ~30 parents of the class of my little son

Actual behavior

TO line "breaks" after appr. 1000 characters:

Root cause analysis:

As K9 runs against my own OpenSuse VPS, with postfix / dovecot etc. running on it, I was able to compare:

Differences:

These are the only differences I can see.

Environment

K-9 Mail version: 5.600

Android version: 6.00

Account type (IMAP, POP3, WebDAV/Exchange): IMAP
