    One of my customers was having problems sending emails from his iPhone (ios 7.1).

    Checking Exim log files I found this error message:
    2014-09-08 19:25:51 dovecot_plain authenticator failed for ([]) []:64358: 535 Incorrect authentication data (

    Fortunatelly I found this article and the solution seemed to work
    535 Incorrect Authentication Data « Support Portal

    However I can´t understand why I had to make this change to have the configuration work in his phone
    if I could send email without problems with my phone since the first moment.

    Is it possible that other users had the same problem?

    Hello :)

    To clarify, repairing the mailbox permissions resolved the issue? If so, it simply means the permissions/ownerships for email files/directories for the account were invalid. Running the script corrected them for that account.

    Thank you.

    I have seen these errors with iPhones too.The problem is in the logfile but the user didn't had a problem sending emails. You posted a dovecot logfile not exim. Are you using SMTP Auth? Or still AUTHRELAY via POP or IMAP?

    Not sure if it is a glitch in iOS or dovecot. The whole iOS email client is a bit strange. E.g. changing the Port for SMTP take minutres.
    Still wondering what iOS is checking for so long.
