You do not seem to have an MX record published for the alumni-office.swarthmore.edu domain and while an A record is acceptable for a machine with a public IP number it is indicative of a possible failure for your network to be configured so as to allow SMTP connection to port 25 on that machine.

I also found that attempting to connect to port 25 on alumni-office.swarthmore.edu failed with a timeout which suggest that something may be blocking connections to it. I suggest you discuss this with your local sys admin as the cause of your problem may be the configuration of firewalls on your machine/LAN

The following illustrate the inability to connect, which is what the MTA that sent the bounce message was reporting:

;; ANSWER SECTION:
alumni-office.swarthmore.edu.  2h5m45s IN A  130.58.82.74

$ telnet alumni-office.swarthmore.edu 25
Trying 130.58.82.74...
telnet: connect to address 130.58.82.74: Operation timed out
telnet: Unable to connect to remote host

I'm not sure if this is a problem on the listserv side.or if bowdoin edu's.
I didn't see anything about this on previous postings, so I thought I'd ask.
Basically, whenever this user tries to post to our listserv, it waits 2 days
and says it can't deliver. I never see the email to be able to approve it.
We don't seem to be having any other problems.just this one user. Thanks in
advance.
