I checked one of my mail servers and noticed that there are delayed emails being delivered to certain mailboxes. The xdelay is not that late, but the delivery to the mailbox is quite too long. Im using sendmail 8.14. I also have filtering in place, the SORBS and SPAMCOP dnsbl
Im using a server with 2GB RAM and dual CPU Intel Xeon 3.0 GHz. Does anybody have an idea why there are such delayed emails? Some emails reaches mailboxes say 3 or 4 seconds delay only though.
I modified the real emails and domain to protect my clients.
