Qmail delivery problem - messages temporarily_deferred sending to yahoo or hotmail
I have a Linux box for shared hosting and got a problem in sending emails.
I've been having a delivery problem whenever I send email to yahoo or hotmail account. There was no bounce back message and I think the messages are being queued, thus very much delayed. When I run /var/qmail/bin/qmail-qstat i receive this,
messages in queue: 4681
messages in queue but not yet preprocessed: 0
In the var/qmail/queue directory, there is a REMOTE directory containing 0 10 12 13 14 15 16 directories. Is this where spam emails are located? Can I just delete the contents of the REMOTE directory?
Could anyone please help me?
