Hi, from a month or so, I started noticing that some mails were delaying for hours before being delivered, after analyzing this, I realized that it was only mails sent to gmail or forwarded to gmail (as some of my customers have their emails just as a forwarding address to their gmail account). I saw a log of a mail being delayed and I have the following log where it is failing and failing and maikng my queue to run for very long and delay mails from/to other users. What can I do? Thank you in advance.
