Very weird.
Taylord, have you checked the quality of your phone line/modem
connection?
Something simple, like an ifconfig, will tell you how many packets are
dropped during a session.
$ /sbin/ifconfig
eth0 Link encap:Ethernet HWaddr 00:00:39:98:B4:9D
inet addr:192.168.0.242 Bcast:255.255.255.255
Mask:255.255.255.0
inet6 addr: fe80::200:39ff:fe98:b49d/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:39497 errors:0 dropped:0 overruns:0 frame:0
TX packets:39530 errors:0 dropped:0 overruns:0 carrier:0
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
HTTPS is a more demanding protocol than HTTP. Packet losses can make a
HTTPS (HTTP over SSL) connection impossible. In addition to the standard
handshake with HTTP, under HTTPS there is public key interchange and
symmetric key and algorithm agreement. Dropping packets at these stages
may be critical to establishing the connection.
Regarding SMTP, I really don't know what to tell you but, again, I would
check a possible noisy phone line.
