Subj : MSGID To : All From : Carlos Navarro Date : Sat Feb 12 2022 09:42 pm 03 Feb 2022 07:25, I asked: CN> Is there any software that has issues with messages having a MSGID CN> like CN> string@z:r/n.p serialno CN> ? So far I have only been told about: - SemPoint - NetMgr (*netmail only) 1. Looks like no one uses SemPoint nowadays. 2. NetMgr only has trouble with netmails. As I've been pointed out, this was reported and discussed in the TUB echo (Dec 2020). I've seen that SBBSecho was changed and currently uses 3D/4D (no "string@" prefix) in MSGIDs for netmails. So it seems that using this type of origaddr's in echomail does not break anything. Carlos --- GoldED+/W32-MSVC 1.1.5-b20180707 * Origin: Costa Blanca, Spain (2:341/234) .
