My system has both of these: [1] EMP: /FIDO/ASIAN_LINK ABS: Maurice Kinal@1:153/7001 BET: MSGID ROT: 2:221/1!153/7001 757 221/6 1 MID: 1:153/7001 8QIOgQad EDA: 20210412014100W+0 LEN: 2042 BEZ: 2:221/1.58@fidonet ef514dc6 MAILER: GNU bash, version 5.1.4(1)-release (x86_64-motorshed-linux-gnu) X_C: X-XP-NTP: 30 F-TO: August Abolins X-XP-Charset: UTF-8 [2] EMP: /FIDO/ASIAN_LINK ABS: Maurice Kinal@1:153/7001.2989 BET: anyway the wind blows ROT: 2:221/1!153/7001 757 221/6 1 MID: 1:153/7001.2989 8QIOgQad EDA: 20210412205200W+0 LEN: 811 MAILER: GNU bash, version 5.1.4(1)-release (x86_64-motorshed-linux-gnu) X_C: X-XP-NTP: 30 F-TO: August Abolins X-XP-Charset: UTF-8 But the subtle difference in these two lines: [1] == MID: 1:153/7001 8QIOgQad [2] == MID: 1:153/7001.2989 8QIOgQad Perhaps you need to keep the "address" part the same for a valid test. -- ../|ug --- OpenXP 5.0.49 * Origin: Mobile?
