When using PassCmd in combination with XOAUTH2, the token generated
might exceed 80 characters and hence would not fit in the buffer
anymore. That leads to a truncated password and an authentication error
later on:
!Error: IMAP wants more steps despite successful SASL authentication.
Increase the size of the buffer to accomodate larger authentication
tokens.
