 * Hello, Thank you for your plugin it’s been very helpful.
 * I’m helping with a website that sends a confirmation at checkout using woocommerce.
   I’d say 99% of the emails go out fine. but in the error logs I see two that happen
   quite a bit.
 * > ERROR PostmanWpMail: Exception code=334 message=Communication Error [334] –
   > make sure the Envelope From email is the same account used to create the Client
   > ID.
 * which doesn’t make sense to me if it works the other 99% of the time.
 * and
 * > ERROR PostmanWpMail: Exception code=0 message=Could not create lockfile /tmp/.
   > postman.lock
 * Do these mean that an email wasn’t sent for each instance?
 * Any idea how I wold go about figuring out this problem?
 * Thanks

 * I am getting the exact same error message.
    Hoping someone can respond to this
   question.

 * Actually, it is the second error message that I am getting.
 * I get it after:
 * PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate
   38213521 bytes) in /home3/lightnm0/public_html/wp-content/plugins/postman-smtp/
   Postman/Postman-Mail/PostmanGmailApiModuleZendMailTransport.php on line 190
 * Maybe that second one always follows another error message?

 * You get the lock file error because Postman crashed while it was trying to send
   mail (the first error), and couldn’t remove its own lock file normally. The lock
   file cleared itself on the next mail attempt.

 * @ winter street
 * Communication Error [334] is an error from Google when it won’t accept your credentials.
   If you’re getting this message 1% of the time, that is quite bizarre, and probably
   points to an error on Google’s side.

 * We switched to using a non-Google email address so this is no longer an issue
   I’m trying to fix. I didn’t mark the topic as resolved since there were others
   asking about it. Thanks.
