How often do you get "I can't mail this person" or "This person can't mail me" queries? ie not user error, but SMTP fuckups, DNS weirdities etc? I'm wondering if one every week or two for a 30-person company means there's an unusual degree of fubar.|
ETA: I presume you all have multiple MXs?
...but I've found a few different companies recently have had that start happening to them...
Just occasional, but its always SMTP errors not finding the domain they are being sent to.
Only common factor I have is that BT are involved in someway usually.
I see that every so often, usually because of a kernel barf on our somewhat flaky IMAP server at Alachua Freenet
. The folks what run UF
's central IMAP and SMTP servers don't usually see much beyond "WHY's my email so [obscene gerund] SLOW??!?!!?" (The usual response is something like, "YOU try feeding 60,000 IMAP mailboxes and spamfiltring an entire University's worth of email on our hardware budget!" :-) ).
Once in a while I do see a bona fide
"SMTP is broken for us!", but it's generally due to the group in question not registering their SMTP server with "the proper authorities" and hence we're not letting that server through our internet boundary ACLs. Technical problems "out there" with SMTP pretty much never come up for us that I've observed.
DNS spasms happen occasionally, but not all that often. DNS related problems usually boil to either a domain's expired, or a hostname's been typo'ed. :-)
