[rt-users] EX_TEMPFAIL for emails containing attachments

[Peter Silver]

Further to my email below, I've run an strace of rt-mailgate after
piping an email containing an attachment into it;

fstat64(4, {st_mode=S_IFREG|0555, st_size=219905, ...}) = 0
old_mmap(NULL, 118584, PROT_READ|PROT_EXEC, MAP_PRIVATE, 4, 0) =
0xb707b000
old_mmap(0xb7096000, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED,
4, 0x1a000) = 0xb7096000
close(4)                                = 0
write(3, "POST /REST/1.0/NoAuth/mail-gatew"..., 226) = 226
select(8, [3], [3], NULL, {15, 0})      = 1 (out [3], left {15, 0})
write(3, "SessionType=REST&action=correspo"..., 49173) = 49173
select(8, [3], NULL, NULL, {15, 0})     = 0 (Timeout)  <---- HANGS
close(3)                                = 0
time(NULL)                              = 1079497347
time(NULL)                              = 1079497347

It seems to get to the stage of sending the HTTP POST, and then times
out after whatever timeout I specify via the --timeout argument.

I don't see any hits to /REST/1.0/NoAuth/mail-gateway in the apache
access log, so I assume the actual HTTP POST is failing.

Any ideas?


thanks,

Peter
