<SPAN lang=EN> <P>Hi! We do use Mercury/32 (4.52) as our mail-gateway. I noticed that several times replies make grow field "References" in header and at some point Mercury/32 does not send this out anymore. I see error "Network write failure during data transmission to" and e-mail is returned. I tried same e-mail against different servers, same. When I'd remove "References" field at all ... it was sent OK. Any ideas, suggestions? I couldn't find much about this via internet. Also, couldn't find how to remove this field at all. And why it grows and why it differs for sending ... Probably this isn't Mercury/32 problem at all, but definitely it is problem for us. Hope You can shed a light to solve this. More thanks, Alar from Tartu Uni, Estonia. </SPAN></P>

Could you post an example set of headers?

<p>This mail looks like it has a dodgy history :)</p><p>There are mulitple Refs added by  <a href="mailto:018201ca2f8e$fdc09a40$8800000a@infutiknt.mtk.ut.ee">infutiknt.mtk.ut.ee</a> & <a href="mailto:715A902360EF7243851E9CD120339DEE034345A47BDB@vrt-serv-1005.overall.ee">vrt-serv-1005.overall.ee</a>.</p><p>It would seem to have been passed back and forward several times, maybe there is a problen with the routing for your domain? </p>

Hi again and thanks! Yes, a dodgy history! =) Shouldn't be any routing problems because this happen at some point, till then, You see, no problem. When any routing issues appear, shouldn't it appear with earlier state already!? Well', I'm not sure, but e-mail's running smoothly, in general. More thanks, Alar.

<p>Maybe something about that particular mail?</p><p>The Received: headers should show the trail of servers and sometimes the RCPT TO info as well. </p><p>Is there any forwarding between external addresses involved? maybe one mailbox @<a href="mailto:715A902360EF7243851E9CD120339DEE034345A47BDB@vrt-serv-1005.overall.ee">vrt-serv-1005.overall.ee</a> & another @theotherone.ee :)</p><p> </p>

<P>Hi and thanks! Again! Not sure. What I tried, I'd remove by hand some references and tried to send with this: References: <<A href="mailto:!&!AAAAAAAAAAAYAAAAAAAAANpBMFcP2tERtPAAoCR8RfKigQAAEAAAALQlhYuOsuBFmUizQA/39nUBAAAAAA==@mtk.ut.ee">!&!AAAAAAAAAAAYAAAAAAAAANpBMFcP2tERtPAAoCR8RfKigQAAEAAAALQlhYuOsuBFmUizQA/39nUBAAAAAA==@mtk.ut.ee</A>> <<A href="mailto:715A902360EF7243851E9CD120339DEE034345A47981@vrt-serv-1005.overall.ee">715A902360EF7243851E9CD120339DEE034345A47981@vrt-serv-1005.overall.ee</A>> <<A href="mailto:01b001ca1f32$78dee5a0$8800000a@infutiknt.mtk.ut.ee">01b001ca1f32$78dee5a0$8800000a@infutiknt.mtk.ut.ee</A>> <<A href="mailto:715A902360EF7243851E9CD120339DEE034345A47987@vrt-serv-1005.overall.ee">715A902360EF7243851E9CD120339DEE034345A47987@vrt-serv-1005.overall.ee</A>>  <<A href="mailto:011501ca1fef$8e8dc160$8800000a@infutiknt.mtk.ut.ee">011501ca1fef$8e8dc160$8800000a@infutiknt.mtk.ut.ee</A>> <<A href="mailto:715A902360EF7243851E9CD120339DEE034345A479D0@vrt-serv-1005.overall.ee">715A902360EF7243851E9CD120339DEE034345A479D0@vrt-serv-1005.overall.ee</A>>  ,<<A href="mailto:026e01ca20c8$56d68d90$8800000a@infutiknt.mtk.ut.ee">026e01ca20c8$56d68d90$8800000a@infutiknt.mtk.ut.ee</A>> <<A href="mailto:715A902360EF7243851E9CD120339DEE034345B2FFD6@vrt-serv-1005.overall.ee">715A902360EF7243851E9CD120339DEE034345B2FFD6@vrt-serv-1005.overall.ee</A>> ,<<A href="mailto:012701ca2254$48cf41a0$8800000a@infutiknt.mtk.ut.ee">012701ca2254$48cf41a0$8800000a@infutiknt.mtk.ut.ee</A>> <<A href="mailto:715A902360EF7243851E9CD120339DEE034345B2FFD7@vrt-serv-1005.overall.ee">715A902360EF7243851E9CD120339DEE034345B2FFD7@vrt-serv-1005.overall.ee</A>>   <<A href="mailto:012001ca26ea$d5421140$8800000a@infutiknt.mtk.ut.ee">012001ca26ea$d5421140$8800000a@infutiknt.mtk.ut.ee</A>> <<A href="mailto:715A902360EF7243851E9CD120339DEE034345A47BD8@vrt-serv-1005.overall.ee">715A902360EF7243851E9CD120339DEE034345A47BD8@vrt-serv-1005.overall.ee</A>> And ... it did the trick! In other means e-mail was same as before. Could it be Mercury can't handle this field at some ... way? No-no, this is not the only one I have with this problem. And also I tried same e-mail send to different servers, same problem. More thanks, Alar.</P>

You will need to provide a complete set of  headers and some real info about your email environment.

<FONT size=2> <P>Hi! And thanks. Nothing much about infra. I try to send a e-mail out from my computer, using Outlook 2003! Via Mercury/32 4.52 (I'd use in between also IMail from Ipswitch, but seems to me, it same happen at end). I see that on some reason in references section appear in middle <tab> ... maybe this? This <tab> character didn't appear in header I sent, I'll attach.</FONT><FONT size=2 face=Arial><FONT size=2 face=Arial><SPAN lang=EN> I can't understand where this <tab> comes from. </FONT></FONT></SPAN><A href="http://infutik.mtk.ut.ee/~alar.sysop/varia/MO0004B7.QDF"><U><FONT color=#0000ff size=2><FONT color=#0000ff size=2><SPAN lang=ET>http://infutik.mtk.ut.ee/~alar.sysop/varia/MO0004B7.QDF</U></FONT></FONT></SPAN></A> <FONT size=2><SPAN lang=ET>More thanks, Alar.</P></FONT></SPAN>

<P>Forgot. ASSP is working together with Mercury/32. Alar.</P>

<p>I tried to see what RFC 2822 has to say about the References header. As far as I can see it's OK to have any number of message references listed in it, but I'm not sure that comma is allowed between references, and each line should not exceed 998 characters. Header folding is OK, though.</p><p>/Rolf </p>
