The text part was sent encoded as quoted-printable, and a line containing "main.c" was wrapped immediately before the ".c", which became the start of the next line. Somewhere along the way, that was interpreted as dot-stuffing, and the dot was removed.

Oh, never mind, I remember now--it's the crappy POP server:

connected to inbound.att.net
connection is encrypted
R '+OK Hello from jpop-0.1'

Better than not wrapping a '.' might be to encode it (=2E) when it begins a line?
