I thought gmail used port 587

StormyWaters is right if you want to send an email from your GMAIL account.

... Unless you want to send an email to a gmail account, in this case the MX lookup of Server with port 25 is

5 gmail-smtp-in.l.google.com 74.125.65.27 60 min SMTP Test Blacklist Check
10 alt1.gmail-smtp-in.l.google.com 74.125.113.27 60 min SMTP Test Blacklist Check
20 alt2.gmail-smtp-in.l.google.com 209.85.143.27 60 min SMTP Test Blacklist Check
30 alt3.gmail-smtp-in.l.google.com 209.85.229.27 60 min SMTP Test Blacklist Check
40 alt4.gmail-smtp-in.l.google.com 74.125.79.27 60 min SMTP Test Blacklist Check

If you have discrepancy between 2 servers then I suggest looking at your firewall...
