VZW + Outlook2003 + SMTPS? MTU? Proxy?
- From: E.B. Dreger
- Date: Mon Mar 22 11:12:05 2004
Has anyone encountered
Mar 17 14:24:01 mail postfix/smtpd: SSL_accept
error from unknown[188.8.131.52]: -1
Mar 17 14:24:01 mail postfix/smtpd: warning: Write
failed in network_biopair_interop with errno=32:
or similar using Outlook 2003 and SMTPS? Outlook reports a
connection timeout, though Postfix obviously is seeing packets.
I'm trying to determine why Outlook thinks Postfix isn't there,
and why Postfix thinks the SSL negotiation was aborted.
The op content: I'm asking in particular if any proxying[*], MTU
issues, or other network creativity is known on the VZW network.
PMTUd works on the Postfix end.
I don't have the VZW-connected machine handy ATM to test further.
SMTPS on that machine works correctly on non-VZW providers. I
don't know about HTTPS, so I admittedly can't rule out PKI fun.
[*] Yes, I know it would be foolish and futile to try proxying
TCP/465 at the app level.
