error sending emails / authenticating to SMTP

    Hi all,

    I’ve just managed to find a solution to an undocumented issue I’ve had for several months. This otherwise brilliant and most useful plugin started throwing errors and not send any email at all from one point. Not to go into details, turned out the issue was linked to the use of certain characters in the password field that didn’t encode / encrypt well. So my 3rd party provider was returning SMTP errors (“Incorrect authentication data”, “Password command failed: 535 Incorrect authentication data”, “Could not authenticate”) despite the fact that the login information was valid and tested. Upon resetting the password and exclude non-ascii characters the service came back online.

    Surely this is not an isolated issue and others will look for a fix that is not all that obvious. This information should be included in the description of the plugin for other to see. I hope this will help others in need.

    Cheers

    Marius

    Hi,

    Thanks for bringing this up.
    We did have such issue prior to 1.4.1.
    In WP Mail SMTP 1.4.1 we modified the way we work with passwords and backslashes/etc should work fine now in passwords.
